Falcons are the stealth fighter jets of the bird world. Recording some of the fastest speeds of all winged animals, these dynamic flyers are captivating to watch.
There are four species of falcons that can be found in South Dakota on an annual basis, and one that is quite rare for the state. Here are the five species of falcons that can be found in South Dakota.
American Kestrel
American Kestrel
Identification
The American Kestrel is a small and colorful bird. Males have a rusty colored back as well as a lighter rusty colored underside. They have blue on their wings and the top of their head as well as black markings near their eye. Females are lighter overall with rusty orange barring on their wings, back, and tail.
Range
American Kestrels live in both South America and North America. In North America, Kestrels are migratory and reside in Mexico in winter, then move into Canada during the breeding season. Throughout much of the United States, American Kestrels can be found year round.
Diet and Foraging Habits
American Kestrels eat small creatures including insects, reptiles, amphibians, birds, and rodents. In terms of the insects they eat, some of the most commonly consumed are grasshoppers, dragonflies, and cicadas.
Where to Find this Bird
American Kestrels are a common sight along roadsides and in open fields. They can be seen on telephone poles and wires in addition to perched on dead trees and other structures in areas with few trees. Other places Kestrels can be found are urban parks, pastures, and farm fields.
Gyrfalcons come in two different color morphs. Living in the high arctic is the white morph which essentially looks like someone took the look of a Snowy Owl and put it on a large falcon. They are pure white with black markings on their wings. The gray morph typically lives farther south and has a gray back and head with dark barring on the underside. They have dark teardrop markings underneath the eye.
Range
Gyrfalcons breed in the arctic with some migrating into the Northern United States to spend the winter. There is a population that lives in mid to Northern Canada and Alaska that most likely stay in the same area year round.
Diet and Foraging Habits
Gyrfalcons feed mostly on medium sized birds such as ptarmigans and seabirds. They will also eat mammals such as lemmings and typically dive onto prey from above.
Where to Find this Bird
Gyrfalcons are most typically found in the continental United States in winter. They like open spaces such as tundras and coastlines where they can survey for prey.
Merlin

Identification
Merlins are very small members of the falcon family looking similar in size to a Mourning Dove. They have a blueish gray to black back, wings, and head, and a buffy to brown streaked underside. Merlins can differ in color based on region but always maintain a somewhat similar appearance. Most of the time they will have a white eye brow stripe.
Range
Merlins winter in Northern South America, Central America, Mexico, the Southeastern United States, and most of the Western United States. In spring they migrate north ending up in only the most Northern parts of the U.S. and much of Canada and Alaska. There is an area from the Northwestern part of the United States to the Southwestern part of Alaska where Merlins live year round. Some individuals stay all winter in Northern states as well.
Diet and Foraging Habits
Merlins primarily eat small birds such as waxwings, sparrows, and even shorebirds. In addition to birds, they also eat insects and rodents.
Where to Find this Bird
Merlins can be tricky to find as encountering one typically seems like a matter of luck. They can be found in wooded areas as well as in open areas where they will be surveying for food. Sometimes the easiest way to see them is in flight when they will be moving at high speeds.
Personal Experience: It seems like if I ever go out intentionally trying to find Merlins there aren’t any around. Each year I typically find one by chance while out birding. It seems that even though they aren’t necessarily supposed to winter in the northern U.S. that is when I see them most.
Peregrine Falcon

Identification
Peregrine Falcons are iconic birds with a dark back, wings, head, and neck. They have a light underside with dark barring and noticeable bright yellow legs. This species has interesting facial markings that some people refer to as “sideburns” but is essentially dark coloration coming down below the eye onto the cheeks of the bird.
Range
The Peregrine Falcon’s range in North America is complicated with a general pattern of wintering in the Southeastern United States and Mexico, summering in Northern Canada, and migrating throughout the rest of the continent. However, there are many places in the continental United States that Peregrine Falcons breed in during summer (such as along Lake Superior) and live year round (such as most of the Pacific Coast, and around the Great Lakes).
This species not only lives in North America, but every other continent as well with the exception of Antarctica.
Diet and Foraging Habits
Peregrine Falcons are the fastest fliers in the entire animal kingdom reaching normal speeds of around 70 miles per hour and a diving speed of around 200 miles per hour. They use this incredible speed to hunt medium sized birds such as doves and ducks, but they have been observed taking on an extremely wide array of different bird species. Peregrine Falcons will also eat fish, and mammals.
Where to Find this Bird
Peregrine Falcons have adapted well to human habitation and use skyscrapers as nesting sites. In more wild areas they will use cliffs as nest sites. Peregrine Falcons can be reliable sights in places where people have placed nest boxes specifically for the species to breed in. Often times these places have corresponding nest cams.
Prairie Falcons have a light brown back, wings, and head with a white underside barred with brown. They have a different facial pattern than the Peregrine Falcon with a brown teardrop marking below the eye that contrasts the pure white of the cheeks and chin.
Range
Prairie Falcons are birds of the Western United States, living year round in most states west of Minnesota and Louisiana year round. They also live in parts of Mexico and Southwestern Canada year round. In winter, some individuals move east into more of the Great Plains states.
Diet and Foraging Habits
Prairie Falcons eat many different small mammals in addition to insects and birds. Like most falcons, they have quite a varied diet in terms of the bird species they eat.
Where to Find this Bird
True to their name, Prairie Falcons live in open spaces such as grasslands, open fields, tundra, and farmland. They nest in places with bluffs and cliffs but often are most easily seen hunting. Prairie Falcons are often on the move and cruise the open spaces looking for food. They can also sometimes be seen perched on branches or telephone poles.
Summary
Falcons are always entertaining to see, and knowing which ones to expect in the state can be a key part of correctly identifying the bird you are seeing. If you enjoyed this post, please give it a like and a comment. Also be sure to check out the Badgerland Birding YouTube Channel.
When thinking about animals that migrate, some the first ones that come to mind are birds. Many bird species migrate in a similar way that involves breeding in more northern areas, then flying south for the winter. There are some species however, that migrate in a different way, which can lead to something called an Irruption.
Irruptions are times when a particular bird species suddenly moves into an area in great numbers. Not every species can have these irruptive migrations however. In general birds that breed and reside in the boreal forests are most known for these mass movements. Some of the species include finches such as redpolls and crossbills, as well as more common backyard birds like blue jays and red-breasted nuthatches. You may remember years when these species were more plentiful In your neck of the woods or maybe they were even downright abundant. This is because of an irruptive year.
Check out this video about finding Purple Finches
While these events can seem random, there actually is a method to the madness. Some irruptive species rely on crops of different seeds for food. If these plants have poor crops, the birds that rely on them have no choice but to move, causing an influx of birds in other parts of their range, or even places they don’t normally live. Since different species rely on different types of cones, its’ possible to have one or two species with irruptive movements, while others remain very scarce in the same area. A larger irruption can occur if food during the summer breeding months was plentiful, thus allowing birds to raise many chicks, but then scarce in fall and winter, meaning there is high demand for food, but a low supply. This causes a massive movement of birds. If the food supply is high, and the demand is low, then the birds stay put. However, there are some other factors at play with these movements, such as sever weather, especially snow and freezing rain. If the food is available but covered in a layer of ice, this can also cause birds to move
Obviously, birders and nature enthusiasts get excited about irruptive species, especially when they get to see them in their home state. Fortunately, there’s a way to try and figure out which species will be on the move ahead of time. The winter Finch Forecast is a report originally created by Ron Pittaway that looks at information from northern cone and fruit crops, and predicts which birds will be on the move during the fall and winter. Tyler Hoar picked up the mantle and now leads the charge in creating the annual winter Finch Forecast along with help from Matt Young and the Finch Research Network as well as many other volunteers all going out to survey both birds and cone crops.
Check out this video on finding Red-breasted Nuthatch
The forecast is then posted, usually in early fall, and birders can start gearing up for what to expect, although weather can cause the forecast to change without much prior notice.
It’s worth noting that it’s not just finches and other song birds that can have irruptive migrations, but also many raptor species too. Raptor irruptions work In a very similar way but instead of fruit and cone crops being the driving force its typically small mammals such as lemmings. Among the more iconic irruptive raptor species are owls, especially the Snowy Owl, which can move into the lower 48 states in larger or smaller numbers during the winter based on the lemming population in the north, as well as how many owl chicks were raised during the breeding season.
Overall, irruptive bird species are very unique in the way they move and can add a lot of excitement to the fall and winter due to their variability. If you’re interested in learning more about these species, check out our videos about them and be on the lookout for the Winter Finch forecast.

Identification
Black-billed Cuckoos have a brown head, back, wings, and tail with a white underside. As their name would suggest, they have a black bill and a red eye.
Range
Black-billed Cuckoos winter in the northwestern part of South America. In spring they migrate north into northeastern and northcentral United States along with southern Canada.
Diet and Foraging Habits
Black-billed Cuckoos feed primarily on insects (especially caterpillars). In nonbreeding season, they also eat fruits and other plant matter such as seeds.
Where to Find this Bird
Black-billed Cuckoos are found in forests, edge habitat, woodlands, and marshes with numerous trees. They can be extremely elusive and are difficult to get eyes on even if they are in the area.
Yellow-billed Cuckoo

Identification
Yellow-billed Cuckoos have a brown head, back, and wings. Their long tails are black with white at the end of the feathers giving their tails a spotted appearance. These birds have a clean white underside and a yellow bill with some black on the upper mandible.
Range
Yellow-billed Cuckoos winter throughout most of South America with the exception of the most southern and western parts of the country. In spring, they move north inhabiting the Carribean, parts of Mexico, the eastern United States, southeastern Canada, and seemingly random pockets in the western United States.
Diet and Foraging Habits
A large portion of the Yellow-billed Cuckoos diet consists of caterpillars. They will often find large quantities of tent caterpillars, fall webworms, and spongy moths. Aside from caterpillars they will also eat other types of insects and small invertebrates along with some types of fruits and seeds.
Where to Find this Bird
Yellow-billed Cuckoos frequent woodlands (especially woodlands with water nearby), scrublands with thick bushes, and even stands of trees in otherwise more open areas.
Summary
Cuckoos are goofy and elusive birds that are always fun to see in the field but can sometimes be tough to identify. We hope this post has helped you learn about and identify the Cuckoos of South Dakota.
Cormorants are slender diving waterbirds with a distinctive shape and set of habits. While there are many cormorant species that live in North America, there are only two that can typically be found in South Dakota, with one being extremely abundant and the other being quite rare. Here is everything you need to know about these two species.
Double-crested Cormorant
Double-crested Cormorant
Identification
Adult Double-crested Cormorants have a dark brown to black head, neck, back, underside and wings. Juveniles will be lighter brown in color with a lighter throat and underside. Both adults and juveniles have orange by the eyes and base of the bill as well as a turquoise colored eye. Breeding adult birds have two tufts on their head that can sometimes be hard to see, but these crests are what this species is named for.
Range
Double-crested Cormorants live year round along the Pacific Coast of North America from Northwestern Mexico all the way up to the Aleutian Islands of Alaska. They also live year round in parts of Florida. This species winters in in the Southeastern United States and Northeastern Mexico. In spring, they move into the Northern United States and Southern Canada where they can be seen migrating in large flocks.
Diet and Foraging Habits
Double-crested Cormorants primarily eat fish which they catch by hunting them underwater. They will also eat other aquatic creature such as crustaceans and amphibians.
Where to Find This Bird
Double-crested Cormorants can be found in a variety of places with all of them usually being near bodies of water. Look for this species in trees lining lakes and ponds as well as in marshes. Often times, Double-crested Cormorants will congregate in large groups on islands or other places with adequate perches as they dry their wings and survey for prey.
Neotropic Cormorant (Rare)

Identification
Neotropic Cormorants are small members of the cormorant family. Adult birds are a shiny black color with white feathers on their head, back, and wings. They have a white triangle on the base of the bill known as a gular. Neotropic Cormorants have yellowish orange on the base of the bill and a turquoise colored eye. Juveniles are lighter in color overall, sporting brown coloration instead of black.
Range
Neotropic Cormorants live year-round in South America, Central America, much of Mexico, and the Gulf Coast of the United States. While much of the population is not migratory, some birds move north in spring and have a habit of turning up north of their normal range.
Diet and Foraging Habits
Neotropic Cormorants eat mostly fish, but will also consume insects, crustaceans, and amphibians. These birds are sight feeders and search for prey underwater where their streamlined bodies make them adept swimmers.
Where to Find This Bird
Neotropic Cormorants live in a wide variety of places including inland lakes, saltmarshes, and along ocean coastlines. They can often be seen perched in branches and other structures near water keeping watch for food.
For information on how to differentiate a Double-crested Cormorant from a Neotropic Cormorant click here to read an article on the subject or check out the video below.
Neotropic vs. Double-crested Cormorant
Summary
Cormorants are unique, lanky birds that are a common sight near the water. Knowing the habits, range, and key identification features of each of these species can be incredibly useful in knowing what to look for in the field.
Owls are extremely charismatic species beloved by both birders and non-birders alike. Nocturnal, mysterious, and secretive, these birds play important roles in our culture.
There are eight species of owls that can be found in Virginia with some being found quite frequently and others being rare visitors. Here are the owl species to be on the lookout for if you are in this state.
Barn Owl (Uncommon)
Barn Owl – Photo by Many Wonderful Artists
Identification
Barn Owls have are a thin looking owl species with an orangey tan and gray back, head, and wings. They have a light underside and pale heart shaped face.
The call of the Barn Owl is a violent sounding scream. It’s possible that legends of creatures like banshees and screaming ghosts derived from people hearing the haunting calls of Barn Owls at night.
Range
Barn Owls reside in most of Mexico and the United States yea- round with the exception of some of the states in the Northern part of the country. Even in the Northern states where their range either does not extend or does not extend very far into, a few individuals of this species can still be found.
Diet and Foraging Habits
Barn Owls hunt almost exclusively at night. Due to this, they eat mostly other nocturnal animals, especially rodents. Voles, mice, shrews, and rats are all creatures that are common prey items for Barn Owls. In addition to small mammals, Barn Owls will also eat small to medium sized birds.
Where to Find This Bird
Barn Owls live in open areas with plenty of space to hunt. Some common places to find them are agricultural fields, grasslands, deserts, and even more urban environments such as cities. As their name suggests, they can be found roosting in barns as well as tree cavities and other structures.
Barred Owl
Barred Owl
Identification
Barred Owls are bulky with round heads, white undersides with brown stripes, and brown backs. They also have white striping on their backs, and dark eyes typically looking uniform in color. Like many owl species, Barred Owls have a flat face known as a facial disk.
Barred Owls have a very distinctive call as they make a “who cooks for you” call. They are known to call even when it’s light out.
Range
Barred Owls are non-migratory and can be found yea- round in the Eastern United States, Southern Canada, and the Pacific Northwestern states of the US. Many of the Western states do not have resident Barred Owls in the wild.
Diet and Foraging Habits
Barred Owls eat many different types of small and medium sized creatures including mammals, other birds, amphibians, and reptiles. They have even been cited going into the water to catch fish and crustaceans. Barred Owls typically find a good vantage point and watch for potential prey items, they will then swoop down from above to catch their meal.
Where to Find This Bird
Badgerland Birding searches for a Barred Owl in an old growth forest
Look for Barred Owls in forests (conifer or deciduous) where there are plenty of tall trees to perch in and cavities to roost in. Older forests with taller trees are typically preferable. Swamps are also good places to find this species, especially in the Southeastern states.
Barred Owls are a species that will call during the daytime so listen for their classic “who cooks for you” call even when it’s light out.
Eastern Screech Owl
Red morph Eastern Screech Owl
Identification
Eastern Screech Owls are small, round looking birds with pointed ear tufts. They come in two different colors or “morphs,” with one being gray and the other being orange. Gray morph birds are very well camouflaged as they look almost exactly like bark with a light gray base color and darker patterns on the back, head, and underside. The orange version of the Eastern Screech Owl is known as a “red morph” bird and have a deep reddish orange base color with darker grayish black patterning on their back, head, and chest. Red morph birds have white coloration on their underside going from the throat down toward their legs.
Range
The aptly named Eastern Screech Owl can be found year-round throughout the Eastern half of the United States and Northeastern Mexico. They also make it into some parts of Southeastern Canada as well. The range of this species expands as far west as Montana, Texas, and Eastern Colorado.
Diet and Foraging Habits
Eastern Screech Owls eat a wide variety of small prey items including mammals, insects, crustaceans, amphibians, and reptiles.
Where to Find This Bird
Eastern Screech Owls are not at all picky about where they live. They can be found in all different types of forests including deciduous and coniferous, residential areas such as city parks, areas near rivers and streams, and edge habitat. They live almost anywhere with adequate tree cover. Often times, Eastern Screech Owls use the same roosting sites repeatedly, meaning that they are easy to find if you know where they are roosting. Look for them peaking out of tree cavities or nest boxes sunning themselves, or watch these same places and wait for them to pop out just before dusk when they usually stick their faces out of their roosting site and wait for the right time to take flight for a night of hunting.
Great Horned Owl
Great Horned Owl
Identification
Out of all of the Owl species in North America, the Great Horned Owl is probably the one that people encounter the most. They are quite large with very noticeable ear tufts and have varying shades of brown covering their back, head, and wings. the Underside of the Great Horned Owl is lighter with a brown wash and darker brown to black horizontal barring.
Great Horned Owls of the arctic population are much more pale and even sometimes look white in color with the same barring and patterns as their southern counterparts.
Range
The Great Horned Owl is extremely widespread across North America as their range encompasses most of Alaska and Canada, the entire continental United States, and the majority of Mexico. They also live in various parts of South America too. This species is non-migratory.
Diet and Foraging Habits
Great Horned Owls eat an extremely wide variety of different animals ranging from small rodents to significantly larger mammals such as skunks and porcupines. They will also eat fairly large bird species such as ducks and even other raptor species. One interesting and gruesome habit of Great Horned Owls is to decapitate their larger prey.
Where to Find This Bird
Great Horned Owls can be found in a variety of different habitats including coniferous forests, deciduous forests, swamps, and residential neighborhoods. The easiest way to find this species is to listen for them making their call: a low “hoo hoo.” During breeding season owls can often be heard calling to one another, a practice known as “dueting.”
Long-eared Owl (Rare)
Long-eared Owl
Identification
Long-eared Owls are medium sized owl species with very large ear tufts. They are brown on the back, wings, and head with orange, tan, and darker brown colors mixed in. Their underside is brown, white, and orange, giving them the appearance of the bark of a pine tree. Long-eared owls have orange facial disks outlined by dark brown.
Range
Long-eared Owls winter in Mexico and the Southern United States. In spring they move into the Northern United States and Southern Canada. There are many states in which Long-eared Owls are year-round residents such as Utah, Nevada, Wisconsin, Michigan, New York, and many more.
Diet and Foraging Habits
Long-eared owls eat a variety of small rodents. They have also been known to consume birds as well. This species hunts for food in open areas where they typically capture prey on the ground.
Where to Find This Bird
Long-eared Owls are secretive birds that roost in thick tangles of brush and vegetation. They often roost in groups so if you happen to find one of these well camouflaged owls, others are most likely around. Some of their favorite trees to nest in are willows, cottonwoods, and tamaracks. Long-eared Owls can also be found by listening for their deep “hoo” calls often repeated in quick succession.
Northern Saw-whet Owl (Uncommon)

Identification
Northern Saw-whet Owls are a very small species with a large, round head. They have a brown back and head with white spots, a white underside, and light brown vertical stripes. They have a white facial disk and piercing yellow eyes.
Range
Northern Saw-whet Owls live year round throughout different parts of North America including Southern Canada, the Northeastern, Northwestern, and Midwestern United States in addition to select areas of Mexico. During winter, they end up filling in the other parts of the United States that they don’t inhabit the rest of the year, moving as far south as Texas and Louisiana some years.
Diet and Foraging Habits
Northern Saw-whet Owls eat small prey items such as mice. They also eat other small mammals and small birds.
Where to Find This Bird
Northern Saw-whet Owls can be found in forests ranging from deciduous to coniferous. They are notoriously difficult to find as they don’t usually use the same roost. To try and locate one, search pine stands (this bird seems to prefer roosting in conifers) and look for white- washed branches. Another way to find Saw-whet Owls is to listen for their call between late winter and spring which sounds like a drawn out “toot toot” repeated in succession.
Snowy Owl (Rare)
Snowy Owl
Identification
Snowy Owls are iconic and recognizable birds. Adult males range from pure white to white with a few dark brown markings. Female and immature birds are white with much more dark barring. These birds always have a white face regardless of the age of the bird.
Range
Snowy Owls breed on the tundra of the high arctic. During fall and winter they descend into Southern Canada, Alaska, and much of the continental United States. Just how far these majestic birds will go is dependent on food sources in the north. While this can be somewhat complicated, it generally boils down to the more food availability during breeding season, the more owls are successfully raised in a given year. The more owls that are raised in the north, the more they spread out, thus leading to what’s known as an irruption in which many owls spread out farther south into the United States than usual. The typical southern range for these birds encompasses the states bordering Canada.
Learn about the patterns of Snowy Owl migration and irruptions
Diet and Foraging Habits
Snowy Owls feed primarily on small rodents. In particular, they are fond of the lemmings that live in their breeding areas. This species will also eat birds as well with waterfowl being a usual menu item.
Snowy Owls hunt on open landscapes and often times sit for hours surveying their surroundings and watching for small rodents.
Where to Find This Bird
Badgerland Birding searches for Snowy Owls along the Lake Michigan coast
Snowy Owls vary in numbers depending on how good the prior year’s nesting season was. In their normal range they can be found in open areas such as farm fields, tundra, and grasslands. The best time to look for Snowy Owls is during an irruption year when many more birds are coming down from the north and flooding into the United States. During these times, Snowy Owls can actually be quite easy to find and end up in slightly more eclectic places such as lake shores and airports.
Short-eared Owl
Short-eared Owl
Identification
Short-eared Owls are colored the same as the prairies and grasslands in which they reside. They have a light sandy colored back, wings, and tail with dark brown mottling. They have a cream colored underside with vertical stripes. This species has a white facial disk with both dark and sandy coloration just below their bright yellow eyes.
Short-eared Owls are highly maneuverable and acrobatic in flight, flying with rapid wingbeats that make them look moth-like. When flying, their flat faces are quite evident and help in separating them from other species such as Northern Harriers.
Range
Short-eared Owls are a species found across the globe in almost every continent. In North America, they winter in Northern Mexico and the Southern United States then move into the Northern Great Lakes states, Canada, and Alaska to breed in the summer.
Diet and Foraging Habits
Short-eared Owls eat small mammals such a slice, lemmings, shrews, and voles. They will also eat small to medium sized birds. Short-eared Owls are specialized hunters that acrobatically fly over open prairies keeping an eye out for ground dwelling mammals. They spend much more time in the air hunting compared to most other owl species.
Where to Find This Bird
Badgerland Birding scours a frozen marsh to find Short-eared Owls
Short-eared Owls can be found in open prairies and grasslands flying low over the landscape. The timing can be important when looking for Short-eared owls as they are crepuscular, meaning they are out most at dawn and dusk. However, there are times when they have been documented flying during the day as well.
Summary
Owls are enigmatic and beautiful birds that are always a treat to see when out in the field. Knowing the species that are expected in your state can be instrumental in identifying which one you’re looking at and understanding their behaviors. Hopefully, this article has helped to answer some questions about the owls of Virginia.
Nightjars are very interesting birds that are characterized by their superb camouflage and nocturnal lifestyle. Many of these species are familiar due to the sounds they make at night rather than what they look like and play an important role in the symphony of nighttime sounds that people hear.
In Virginia, there are three nightjar species that can be found in the state. Knowing what these species look like, sound like, and some of their habits can be instrumental in knowing which one you have encountered.
Chuck-will’s-widow

Identification
Chuck-will’s-widows are camouflaged to look just like a tree branch with a base gray to brown color with darker and lighter patches of color mixed in. They have a short, flat, appearance with large eyes and a small bill. Males have light bands of color on their tail that are visible in flight.
Range
Chuck-will’s-widows are classic southern bird species that spend their summers in the Southeastern United States and can be found year-round in Southern Florida. Chuck-will’s-widows migrate south for the winter, residing in Eastern Mexico, Central America, Cuba, and Northeastern South America.
Diet and Foraging Habits
Chuck-will’s-widows are nocturnal hunters that feed primarily on insects, but have also been known to eat small birds and bats.
Where to Find This Bird
Chuck-will’s-widows can be found in scrubby or forested areas across their normal range. They are best found by listening for their call which sounds like they are saying their own name: “Chuck-will’s-widow.”
Common Nighthawk
Common Nighthawk – Photo by USFWS Mountain-Prairie
Identification
Common Nighthawks are compact looking birds with brown, gray, and tan mottled patterning on their back, head, and wings. They have brown stripes on their lighter colored underside, large eyes, and a small bill. Some characteristic markings of Common Nighthawks are white on the wings and under the chin.
Range
Common Nighthawks winter in South America and migrate north in spring. They are widespread across the United States and Canada but do not usually go as far north as Alaska. This species also summers in Western Mexico and lives year-round in Cuba and the surrounding islands.
Diet and Foraging Habits
Common Nighthawks feed on flying insects which they catch out of the air. They often feed near streetlights and other sources of light during the night that are attractors for insects. This species also feeds during the later parts of the daytime as well as the night.
Where to Find This Bird
Common Nighthawks can be found most easily by watching for them during migration when they can sometimes be seen in large numbers flying over during the late afternoon and early evening. Other ways to see these birds are to look out for them near large lights such as streetlights and stadiums where they will be looking to feed on insects that are attracted to the lights. Even if it’s dark out, listen for the sharp “beer” call of these birds to know that they are around.
Eastern Whip-poor-will
Eastern Whip-poor-will – Photo by Susan Young
Identification
Eastern Whip-poor-wills are a base brown color with lighter tan, gray, and darker brown mottling, making this species look like a log or tree branch. They have darker barring on a light underside, large eyes, and a small somewhat downturned bill.
Range
Eastern Whip-poor-wills winter in Central America, Eastern Mexico, and the Gulf Coast of the United States. In spring, they move north to their breeding areas in most of the Eastern United States and Southeastern Canada. There are some parts of the Eastern United States that Eastern Whip-poor-wills migrate through but do not spend the summer in.
Diet and Foraging Habits
Eastern Whip-poor-wills feed on insects. They will leave their perches to catch moths, beetles, and other flying insects out of the air and then return to the same perch. Since this species has a surprisingly large mouth, they can eat insects that are fairly sizable.
Where to Find This Bird
Eastern Whip-poor-wills can be found in forests close to more open areas such as fields. The best way to find them is to go out at night and listen for their namesake “whip-poor-will” call.
Summary
Nightjars are enigmatic and mysterious birds that aren’t often seen due to their nocturnal nature. Knowing the species that are expected in your state can be instrumental in identifying which one you are looking at or hearing. Hopefully, this article has helped in answering some questions about the nightjars of Virginia.
Geese can be loud, but also beautiful birds that can be found throughout North America. Since there are only a handful of species that call the United States home, geese can be a good group to start with if you’re just beginning to learn bird identification. Both males and females of these species look the same as far as plumage, and they do not have different colorations in different seasons.
Virginia is home to many different goose species with some being common and others being rare. Here is everything you need to know about those species.
Brant
Brant
Identification
The Brant is a medium-sized goose that is smaller than a Canada Goose, but larger than a Mallard duck. They have a black head, stubby black bill, black neck and upper chest, with a brown and white body, white rump, and black wingtips. They have a characteristic white mark on their neck that can be variable in size and shape.
Range
Brants normally migrate through parts of the western and northeastern United States and parts of Canada, with some wintering populations on the east coast and in Alaska. They nest in the arctic wetlands of northern North America.
Diet and Foraging Behavior
Brants feed mostly on vegetation such as grasses, sedges, and aquatic plants. In the winter, they eat mainly eelgrass and algae, although in some areas they will also eat other grasses if eelgrass is not available.
Where to Find this Bird
The Brant is rare in most midwestern states. Keep an eye out for this bird in flocks of other goose species, normally found near water or in open grassy areas or farm fields.
Canada Goose

Adult Canada Geese are large birds with a black head and neck, white cheek, brown back and sides, black feet and legs, with a white stomach and rump. They are larger, have a longer neck, and a longer bill than the closely related Cackling Goose. It’s worth noting that there are many different subspecies of Canada Geese that can vary slightly in size and appearance.
Range
Common year-round throughout much of North America, the Canada Goose migrates south in the winter and north throughout the Northern U.S., Canada and Alaska in the summer. Once seen as a majestic migratory bird, many Canada Geese have spread to urban environments and can be seen hissing at those that get too close to them or their young.
Diet and Foraging Behavior
During spring, Canada Geese feed mostly on grasses, and during the fall and winter, they eat mostly seeds and berries.
Where to Find this Bird
Look for Canada Geese near water, in open or grassy fields often in large flocks. They can also be found in and near urban ponds. Look for them flying overhead making the classic goose “honk” and flying in a “V” formation.

Identification
Adult Cackling Geese look very similar to Canada Geese, but with some key identification differences. They have similar color patterns with a black head and neck, white cheek, brown back and sides, black feet and legs, with a white stomach and rump, however they are smaller (about Mallard duck sized) with a stubbier neck, steep forehead, and smaller, more triangular shaped bill. They will often flock with Canada Geese, along with other geese species. These flocks can be extremely large during migration.
The Cackling Goose spends winter in the central U.S. and Central America, with some populations near the East and West coasts. Their migratory route spans the central U.S. and west coast, and they migrate to northern North America to breed.
Diet and Foraging Behavior
Cackling Geese feed mostly on plants and plant material such as grasses, sedges, seeds, and berries.
Where to Find this Bird
Look for Cackling Geese near water, in open or grassy fields, and in mixed flocks. Also look for them flying overhead with other goose species, and keep an eye out for noticeable smaller birds, compared to Canada Geese.
Snow Goose

Blue morph Snow Goose (Bill Grossmeyer photo)
Identification
Snow Geese are majestic birds that come in different color morphs. The adult white morph Snow Goose has an all white body, black wingtips, and a pinkish-orange bill with a black “grin patch”. A “grin patch” is a visible space between the upper and lower mandible of the bird seen when the bird’s bill is closed. A “blue morph” Snow Goose is the same size as the white morph with the same bill color, however the body is dark in coloration with variable amounts of white and darker colors along with a white head.
Range
Snow Geese breed in northern North America and migrate through much of North America. They winter in select areas of the United States and Central America, often in large flocks.
Diet and Foraging Behavior
Snow Geese are vegetarians that feed on grasses, shrubs, seeds, berries and more. Sometimes they will eat entire plants.
Where to Find this Bird
Snow Geese can be found in large flocks, mixed in with Ross’s Geese, Canada geese, and Cackling Geese. They are often seen in or near water, or in fields. Keep an eye out for mixed flocks flying overhead in a “V” formation.
Ross’s Goose
Ross’s Goose (Bill Grossmeyer photo)
Identification
Along with Snow Geese, Ross’s Geese also have multiple color morphs. Adult white morph Ross’s Geese have an all white body, black wingtips, and a pinkish-orange bill with a small or absent “grin patch”. A blue morph Ross’s Goose will be the same size as the white morph with the same bill color, however the body will be dark in coloration with variable amounts of white and darker colors along with a white head. A true blue morph Ross’s Goose is very rare, and many are actually hybrid Snow and Ross’s Geese. Keep on the lookout for signs of hybridization such as a bird with a small, triangular bill but a large, dark grin patch. Overall, Ross’s Geese will be smaller than Snow Geese with a smaller, triangular bill that has a gray-blue base, and a stubbier neck.
Range
Ross’s Geese breed in northern North America in colonies and migrate through much of central and western North America. They winter in select areas of the United States and Central America, often in large flocks.
Diet and Foraging Behavior
Ross’s Geese are vegetarians that feed on grasses, shrubs, seeds, berries and more. Sometimes they will eat entire plants.
Where to Find this Bird
Ross’s Geese can be found in large flocks, mixed in with Snow Geese, Canada, and Cackling Geese. They are often seen in or near water, or in fields. Keep an eye out for mixed flocks flying overhead in a “V” formation.
Adult Greater White-fronted Geese (sometimes called Speckled Geese, or Speckle-belly Geese) are brown in color with a white rump, white stripe on their side, white forehead, black spots on their stomach and a bright pinkish-orange bill and legs. They can look similar to Greylag Geese, which are a domesticated species that can sometimes be seen in urban parks, but Greylag Geese will have a thicker bill, be larger and more stout, and have a striped neck.
Range
Greater White-fronted Geese breed in northern North America in colonies, and on the Alaskan tundra, and migrate through much of central and western North America. They winter in select areas of the western and southern United States and central America, often in large, mixed flocks.
Diet and Foraging Behavior
Greater White-fronted Geese feed mostly on plant material such as grasses, berries, sedges, emergent vegetation, and tubers.
Where to Find this Bird
Greater White-fronted Geese can be found in large flocks, mixed in with Ross’s, Snow, Canada, and Cackling Geese. They are often seen in or near water, or in fields. Keep an eye out for mixed flocks flying overhead in a “V” formation.

Cormorants are slender diving waterbirds with a distinctive shape and set of habits. While there are many cormorant species that live in North America, there are only two that can typically be found in Indiana, with one being extremely abundant and the other being quite rare. Here is everything you need to know about these two species.
Double-crested Cormorant
Double-crested Cormorant
Identification
Adult Double-crested Cormorants have a dark brown to black head, neck, back, underside and wings. Juveniles will be lighter brown in color with a lighter throat and underside. Both adults and juveniles have orange by the eyes and base of the bill as well as a turquoise colored eye. Breeding adult birds have two tufts on their head that can sometimes be hard to see, but these crests are what this species is named for.
Range
Double-crested Cormorants live year round along the Pacific Coast of North America from Northwestern Mexico all the way up to the Aleutian Islands of Alaska. They also live year round in parts of Florida. This species winters in in the Southeastern United States and Northeastern Mexico. In spring, they move into the Northern United States and Southern Canada where they can be seen migrating in large flocks.
Diet and Foraging Habits
Double-crested Cormorants primarily eat fish which they catch by hunting them underwater. They will also eat other aquatic creature such as crustaceans and amphibians.
Where to Find This Bird
Double-crested Cormorants can be found in a variety of places with all of them usually being near bodies of water. Look for this species in trees lining lakes and ponds as well as in marshes. Often times, Double-crested Cormorants will congregate in large groups on islands or other places with adequate perches as they dry their wings and survey for prey.
Neotropic Cormorant (Rare)

Identification
Neotropic Cormorants are small members of the cormorant family. Adult birds are a shiny black color with white feathers on their head, back, and wings. They have a white triangle on the base of the bill known as a gular. Neotropic Cormorants have yellowish orange on the base of the bill and a turquoise colored eye. Juveniles are lighter in color overall, sporting brown coloration instead of black.
Range
Neotropic Cormorants live year-round in South America, Central America, much of Mexico, and the Gulf Coast of the United States. While much of the population is not migratory, some birds move north in spring and have a habit of turning up north of their normal range.
Diet and Foraging Habits
Neotropic Cormorants eat mostly fish, but will also consume insects, crustaceans, and amphibians. These birds are sight feeders and search for prey underwater where their streamlined bodies make them adept swimmers.
Where to Find This Bird
Neotropic Cormorants live in a wide variety of places including inland lakes, saltmarshes, and along ocean coastlines. They can often be seen perched in branches and other structures near water keeping watch for food.
For information on how to differentiate a Double-crested Cormorant from a Neotropic Cormorant click here to read an article on the subject or check out the video below.
Neotropic vs. Double-crested Cormorant
Birds that are Similar to Cormorants
There is one North American bird species that technically is not a cormorant, but is similar enough to include it on the list.
Anhinga (Rare)
Anhinga
Identification
Anhingas look extremely similar to cormorants with a long snake-like neck and a long pointed bill. They have longer tails than most cormorant species and show white on their wings. Overall, Anhingas are dark colored with dark brown to black bodies and lighter colored necks.
Range
Anhingas are year-round residents of the northern half of South America, the coasts of Central America and Mexico, and the southeastern coast of the continental United States. In summer, they move farther north and have a tendency to move pretty far north into the eastern United States.
Diet and Foraging Habits
Anhingas primarily feed on fish which they actively hunt for underwater and spear with their sharp, pointed bill. They will also eat crustaceans and other small invertebrates.
Where to Find This Bird
Anhingas can be found in areas with slow moving freshwater such as marshes, bayous, and general wetlands. Look for them drying their wings on perches or swimming in the water, sitting low mostly with just their head and neck above the waters surface.
Summary
Cormorants are unique, lanky birds that are a common sight near the water. Knowing the habits, range, and key identification features of each of these species can be incredibly useful in knowing what to look for in the field.
Nightjars are very interesting birds that are characterized by their superb camouflage and nocturnal lifestyle. Many of these species are familiar due to the sounds they make at night rather than what they look like and play an important role in the symphony of nighttime sounds that people hear.
In Tennessee, there are three nightjar species that can be found in the state. Knowing what these species look like, sound like, and some of their habits can be instrumental in knowing which one you have encountered.
Chuck-will’s-widow
Chuck-will’s-widow – Photo by Susan Young
Identification
Chuck-will’s-widows are camouflaged to look just like a tree branch with a base gray to brown color with darker and lighter patches of color mixed in. They have a short, flat, appearance with large eyes and a small bill. Males have light bands of color on their tail that are visible in flight.
Range
Chuck-will’s-widows are classic southern bird species that spend their summers in the Southeastern United States and can be found year-round in Southern Florida. Chuck-will’s-widows migrate south for the winter, residing in Eastern Mexico, Central America, Cuba, and Northeastern South America.
Diet and Foraging Habits
Chuck-will’s-widows are nocturnal hunters that feed primarily on insects, but have also been known to eat small birds and bats.
Where to Find This Bird
Chuck-will’s-widows can be found in scrubby or forested areas across their normal range. They are best found by listening for their call which sounds like they are saying their own name: “Chuck-will’s-widow.”
Common Nighthawk
Common Nighthawk – Photo by USFWS Mountain-Prairie
Identification
Common Nighthawks are compact looking birds with brown, gray, and tan mottled patterning on their back, head, and wings. They have brown stripes on their lighter colored underside, large eyes, and a small bill. Some characteristic markings of Common Nighthawks are white on the wings and under the chin.
Range
Common Nighthawks winter in South America and migrate north in spring. They are widespread across the United States and Canada but do not usually go as far north as Alaska. This species also summers in Western Mexico and lives year-round in Cuba and the surrounding islands.
Diet and Foraging Habits
Common Nighthawks feed on flying insects which they catch out of the air. They often feed near streetlights and other sources of light during the night that are attractors for insects. This species also feeds during the later parts of the daytime as well as the night.
Where to Find This Bird
Common Nighthawks can be found most easily by watching for them during migration when they can sometimes be seen in large numbers flying over during the late afternoon and early evening. Other ways to see these birds are to look out for them near large lights such as streetlights and stadiums where they will be looking to feed on insects that are attracted to the lights. Even if it’s dark out, listen for the sharp “beer” call of these birds to know that they are around.
Eastern Whip-poor-will
Eastern Whip-poor-will – Photo by Susan Young
Identification
Eastern Whip-poor-wills are a base brown color with lighter tan, gray, and darker brown mottling, making this species look like a log or tree branch. They have darker barring on a light underside, large eyes, and a small somewhat downturned bill.
Range
Eastern Whip-poor-wills winter in Central America, Eastern Mexico, and the Gulf Coast of the United States. In spring, they move north to their breeding areas in most of the Eastern United States and Southeastern Canada. There are some parts of the Eastern United States that Eastern Whip-poor-wills migrate through but do not spend the summer in.
Diet and Foraging Habits
Eastern Whip-poor-wills feed on insects. They will leave their perches to catch moths, beetles, and other flying insects out of the air and then return to the same perch. Since this species has a surprisingly large mouth, they can eat insects that are fairly sizable.
Where to Find This Bird
Eastern Whip-poor-wills can be found in forests close to more open areas such as fields. The best way to find them is to go out at night and listen for their namesake “whip-poor-will” call.
Summary
Nightjars are enigmatic and mysterious birds that aren’t often seen due to their nocturnal nature. Knowing the species that are expected in your state can be instrumental in identifying which one you are looking at or hearing. Hopefully, this article has helped in answering some questions about the nightjars of Tennessee.
Gulls are birds that prove to be controversial in the birding community. Some people despise them for how difficult they can be to identify, while others love them for the same reason.
Here are all of the expected gulls that can be found in Tennessee. along with some that are rare visitors. This article also includes identification tips and information on where to find them.
Herring Gull
Herring Gull
Identification
Herring Gulls are large birds with a white body and head, gray wings, black wing tips, a thick yellow bill, and pink legs. Adult Herring Gulls have a yellow eye while juveniles have a dark colored eye as well as a dark colored bill. Sometimes, sub-adult Herring Gulls will have a mostly yellow bill with black near the tip, making them similar in coloration to a Ring-billed Gull. Juvenile Herring Gulls are darker in color ranging from dark tan, to brown, to gray depending on their cycle.
Range
Herring Gulls are extremely wide spread across the United States. They winter in the Southeastern United States, along the Mississippi River, the Gulf Coast, the East Coast, and the West Coast along the oceans. They can be found year round along the Great Lakes, the Northeastern U.S. and Southeastern Alaska. During spring they migrate through the Great Plains and Western States to get to their breeding grounds in Canada and Central Alaska.
Diet and Foraging Behavior
Herring Gulls feed on many different types of food and have a reputation of eating almost anything including trash, carrion, eggs, and even smaller birds. The majority of their diet however consists of aquatic creatures including fish, mussels, and other invertebrates. Herring Gulls are extremely opportunistic and as a result have an extremely varied diet and are therefore able thrive in wide variety of habitats.
Where to Find this Bird
Herring Gulls are one of the most abundant gull species in the state, especially in winter. Traveling to the ocean coastline in winter will all but guarantee a sighting of this particular species. For a more eclectic birding experience, searching out a landfill is also an easy way to find this species.
Ring-billed Gull
Ring-billed Gull
Identification
Ring-billed Gulls can be identified by their white head and body, gray wings, black wing tips, yellow legs, and yellow bill with a black “ring” around it. Nonbreeding adults look mostly the same as breeding adults but with tan streaking on the head and neck.
Juvenile Ring-billed Gulls are white as a base color with brown and tan mottling. Their bills are pinkish as opposed to yellow and instead of a ring, they have a dark tip of the bill, making them bi-colored.
Range
Ring-billed Gulls are extremely widespread across the United States. They winter in the southern half of the country and migrate north to the Northern half of the country and into Canada, the Great Lakes states, and the Western States to breed. Some Ring-billed Gulls stick around the whole year near the Great Lakes.
Diet and Foraging Behavior
Ring-billed Gulls are not picky about what they eat and will feed on fish, insects, worms, trash, and food given to them by people. Like other gulls they often forage near the water but this species also forages in open fields nowhere near water.
Where to Find this Bird
Ring-billed Gulls are extremely common and easy to find provided it is the right time of the year. In southern states, the winter will be the best time to see this species, and in northern states the summer will be the best. Look for Ring-billed Gulls on beaches, in parking lots and soaring overhead surveying for easy to forage food.
The Bonaparte’s Gull is a small gull species with a very thin, petit bill. They have a white body, gray wings, black wing tips, and reddish pink legs. In breeding plumage, Bonaparte’s Gulls have a black head with white eye crescents, while in nonbreeding plumage they have a white head with a black spot behind their eyes and light pink legs.
Range
Bonaparte’s Gulls winter in much of the southern United States in addition to the Bahamas, Cuba, and Northeastern Mexico. They also winter along the Northwestern coast of Mexico all the way up to the coast of Washington in the West and all the way up to Maine in the East. In spring, this species makes its way North over the United States and ends up in Canada and Alaska where they nest.
Diet and Foraging Behavior
Bonaparte’s Gulls eat a variety of different food items with most of their diet being found in or around water. Some of the things they eat include small fish and medium sized insects in addition to surprisingly small creatures such as zooplankton and tiny invertebrates. These sleek gulls often forage in flocks and dip their bills in the water to catch prey on the fly. They will also forage in both dry and flooded fields and pick through the shallow water or sub-straight.
Where to Find this Bird
Bonaparte’s Gulls can be found in flooded fields and lake shores where they often congregate in large groups. In flight, Bonaparte’s gulls are sleek and acrobatic, looking tern-like as they maneuver through the air. They will also forage and rest along ocean coastlines where they flock with other gulls.
Glaucous Gull (Rare)
Alan Schmierer Photo
Susan Young Photo
Identification
Glaucous Gulls are unique because they are one of the few gulls species that does not have black wing tips but rather white. They are the second largest gull species in the world and in some categories may outclass the larger Great Black-backed Gull such as weight. Adult breeding plumage Glaucous Gulls are very clean looking birds with a white head, white underside, gray wings, a yellow bill, and pink legs.
In nonbreeding plumage Glaucous Gulls look very similar to breeding plumage birds but have brownish streaking on their neck and head.
Juvenile Glaucous Gulls are even paler than the adults with a creamy white color covering their bodies with light brown patterning. Second winter Gloucaous Gulls can show as almost entirely white with very little brown mottling. Sub adult birds will have a pink colored bill with darker brown or black on the tip of it, making it bi-colored.
Range
Glaucous Gulls are very at home in the Arctic, with the most sightings of them taking place in Greenland, Iceland, Northern Europe, Northern Canada, and Alaska. In winter they travel south spending time in the Northeastern United States, the Northern Pacific Coast, and the Great Lakes. They can also be found inland from large bodies of water from time to time.
Diet and Foraging Behavior
Glaucous Gulls are extremely opportunistic feeders. With their large size, they can eat a wide variety of food including fish, aquatic invertebrates, eggs, other birds, carrion, and trash. In the northern part of their range Glaucous Gulls have been known to feed on the remains of polar bear kills a are also recorded as eating the chicks (and also adults) of many different sea dwelling bird species.
Where to Find this Bird
Glaucous Gulls are at home near large bodies of water such as ocean coastlines and the Great Lakes. They can be found loafing on ice or beaches with other species in the winter months (which are the best times to see these large arctic gulls). The coasts aren’t the only places to see Glaucous Gulls however as they can also be seen in inland lakes and landfills.
Great Black-backed Gull (Rare)
Great Black-backed Gull
Identification
The Great Black-backed Gull is the largest gull species in the world and even when compared with other large species such as Glaucous and Herring Gulls look noticeably larger. They have a white head, tail, and underside with a namesake black back as well as black wings and black primary feathers. Great Black-backed Gulls have a robust yellow bill and light pink legs.
Young Great Black-backed Gulls look similar to adults but with dark streaking on the head and underside as well as more of a checkered black and white pattern on the wings as opposed to the solid dark gray or black of an adult. Additionally, Great Black-backed Gulls have dark colored bills as opposed to the bright yellow of adults, but they do still have pink legs.
Range
Great Black-backed gulls are birds of the Atlantic Coasts. They can be found in many northwestern European countries as well as Iceland, Greenland, Eastern Canada, and the Eastern United States. In the U.S. Great Black-backed Gulls are seen most often in winter and typically move out of the continental U.S. during summer although there are some places along the Atlantic Coast where they are found year round.
Diet and Foraging Behavior
Simply speaking, Great Black-backed Gulls will eat anything they can fit in their most including trash, crabs, fish, eggs, carrion, and other birds. They have been known to steal food from other species and eat the chicks of other sea dwelling birds.
Where to Find this Bird
Great Black-backed Gulls are most common in winter when they can be seen loafing on docks, beaches, and ice on the Great Lakes. They can also be seen frequently at landfills. In all of these places they stand out due to their impressive size.
Lesser Black-backed Gull
Lesser black-backed Gull (Ott Rebane Image)
Identification
Lesser Black-backed Gulls can be identified by their white head and body, dark gray to black wings, yellow bill, yellow legs, and dark primary feathers. They look similar in appearance to Great Black-backed Gulls but will be smaller overall and have yellow legs as opposed to the pink legs of the Great Black-backed Gull.
Juvenile Lesser Black-backed Gulls will be pale white or cream with black mottling on their body, head and neck. They have black bills when young and beginning of a dark back forming will typically be evident.
Range
The Range of the Lesser Black-backed Gull spans several continents including Asia, Africa, Europe, North America, and South America. Most of the sightings of this species occur in Western Europe in addition to many sightings occurring in Northern Canada and the United States. In the U.S. Lesser Black-backed Gulls winter in the Eastern half of the country with the most individuals being found near the Atlantic Ocean, but many other sightings occurring inland as well as near the Great Lakes.
Diet and Foraging Behavior
Lesser Black-backed Gulls eat almost anything ranging from fish, to crustaceans, to carrion, to plant matter. Like most other large North American Gull species, Lesser Black-backed Gulls take advantage of human habitation by eating scraps of food and garbage left by humans. They will forage in the water on the fly or walk along beaches, even flipping over rocks and sticks in hopes of finding a meal.
Where to Find this Bird
Lesser Black-backed Gulls are most commonly seen in winter, and are a fairly normal sight along the Atlantic Ocean all the way from the Gulf of Mexico to Maine. They can also be found near the Great Lakes in winter where they flock with other Northern Gull species such as Great Black-backed and Glaucous Gulls.
Iceland Gull
Iceland Gull
Identification
Out of all The North American Gull species, Iceland Gulls are probably the most vexing when it comes to identification. This species consists of what was once two separate species; the Iceland Gull and the Thayer’s Gull. The “Iceland” type Iceland Gull is fairly easy to identify as they have gray wings and back, white head and underside, a yellow bill, and white wing tips. They are smaller and more dainty looking than Glaucous Gulls but clearly discernible from Herring Gulls due to the white primary feathers on the wings. The trouble comes mostly from the “Thayer’s” type Iceland Gulls which can be widely variable in appearance and be extremely close in appearance to Herring Gulls. Thayer’s Iceland Gulls are slightly smaller than Herring Gulls and have a thinner bill. The diagnostic white wing tips of other Iceland Gulls are not present in Thayer’s types but instead are replaced by dark wing tips with lighter undersides of the wing tips, a feature that can be very difficult to see. If unsure about the identification about a Thayer’s type Iceland Gulls, consulting an expert on the individual bird in question is the best choice.
Juvenile Iceland type Iceland Gulls have a white base color with dark mottling while juvenile Thayer’s type Iceland Gulls may be darker overall and will typically have dark wing tips.
Range
Iceland Gulls spend the summer in the Arctic Circle in Northern Canada, Iceland, and Greenland. In winter they move south into Northwestern Europe and the Northeastern United States. This species also shows up along the Great Lakes in winter.
Diet and Foraging Behavior
Iceland Gulls eat mostly fish but will also eat other marine creatures such as crustaceans, carrion, zooplankton, and trash. Like other gull species, they are extremely opportunistic and will eat eggs and young of other birds as well as plant matter.
Where to Find this Bird
Iceland Gulls are most easy to find in winter in the United States where they live on ocean shores and large inland lakes. Another less glamorous place to find them is landfills where they can be found in winter along with many other gull species.
Black-legged Kittiwake (Rare)
Black-legged Kittiwake (Nonbreeding) (Photo by Bill Grossmeyer)
Black-legged Kittiwake with Chicks (Robin Corcoran Photo)
Identification
Adult breeding plumage Black-legged Kittiwake’s have a white body and head with gray wings. They have black wing tips, a slightly curved yellow bill, and namesake black legs. Overall ,the Black-legged Kittiwake is a relatively small gull species.
In nonbreeding plumage adults look almost the same as those in breeding plumage but with black on the back of their head.
Immature Black-legged Kittiwake’s have the same white body and gray wings but have a few extra markings that adults don’t have. Juveniles will show a black spot on their head, a white stripe on their neck, and a black “M” marking on their wings that looks like a black stripe when their wings are folded. Juvenile Black-legged kittiwakes also differ from adults by having a black bill as opposed to yellow.
Range
Black-legged Kittiwakes are birds of ocean coastlines. They can be found along the ocean in Western Europe, Iceland, Greenland, the Eastern United States, Eastern Canada, the Pacific coast of the United States, Alaska, and the Eastern parts of Russia and Japan. Black-legged Kittiwakes are most commonly seen in the United States in winter but can be found in Alaska in summer, and also turn up as rarities in inland states.
Diet and Foraging Behavior
Black-legged Kittiwake’s diet largely consists of small fish in addition to other small marine creatures like jellyfish, zooplankton, and squid. This species has been known to feed near whales and boats where they they can be seen looking for scraps left behind. It’s worth noting that Black-legged Kittiwakes are not known for visiting landfills like many other North American Gull species are.
Where to Find this Bird
Black-legged Kittiwakes are rare in most inland states in the U.S. They are easier to find along the oceans but juveniles will turn up from time to time in the Great Lakes and other bodies of water. Look for a bird that looks somewhat like a non-breeding Bonaparte’s Gull or Little Gull but with the extra black markings.
Laughing Gull

Laughing Gull
Identification
Laughing Gulls are medium sized gulls with a whit underside, gray wings, dark wing tips and a relatively large, deep red, slightly curved bill. In adult breeding plumage this species has a black head with thin white eye crescents.
In nonbreeding plumage, Laughing Gulls look similar but have a darker bill, a white head, and only a small patch of black on their head.
This species can be difficult to distinguish from Franklin’s Gulls but can be done with a little knowledge about what ID features to look at. For more information on this, you can check out our post titled Franklin’s Gulls vs. Laughing Gull. You can also watch our video about the topic below.
Range
Laughing Gulls winter in Northern South America, Central America, Mexico, and some of the Southern states in the United States such as Florida. While many Laughing Gulls reside on the Southeastern Coasts of the United States year round in addition to Cuba and the Bahamas, others migrate north during breeding season ending up in the Northeastern United States and the Great Lakes.
Diet and Foraging Behavior
Laughing Gulls diet’s consist of many different food items including invertebrates, fish, squid, small fruits, carrion, and scraps left by people. They can be seen congregating in places with many humans waiting for free handouts or discarded food.
Where to Find this Bird
Laughing Gulls are extremely common along the Atlantic Coast of the United States and can be seen in high numbers on public beaches, often associating with other species of gulls and terns. To see these birds, simply head to a beach on the ocean and you will have an extremely high chance of seeing them.
Franklin’s Gull

Breeding Franklin’s Gull
Identification
Breeding plumage Franklin’s Gulls have a white neck and underside, gray back and wings, a black hood, and deep red bill. Some of the extra identification features about them to note are the large white spots on their folded black primary feathers, their large white eye crescents, and sometimes a pink wash on their chest and underside (other gull species can show this pink wash as well).
Nonbreeding Franklin’s Gulls look ver similar to breeding plumage birds but instead of a completely dark hood they have a partial faded looking black hood that often still shows their white eye crescents.
Range
Franklin’s Gulls have an interesting range compared to most other North American Gull species. They spend the winter along the Western coast of South America and migrate north in spring. Franklin’s Gulls are not as common along the Atlantic and Pacific Coasts as they are in states such as Texas, Kansas, Arkansas, North Dakota, and South Dakota, but they can still be found along the coasts in migration. This species spends the summer in Southcentral Canada, Montana, and North Dakota.
Diet and Foraging Behavior
While Franklin’s Gulls eat mostly invertebrates such as insects. They will also consume worms, mollusks, small fish, and other small aquatic creatures. Franklin’s Gulls have some interesting foraging habits including twirling in the water to stir up food items, as well as following farming equipment to catch insects.
Where to Find this Bird
Franklin’s Gulls are an uncommon but expected migratory bird in most states with the peak time to view them typically being the later weeks of May or first weeks of June. They are more common in the Great Plains states where they occur in fairly large numbers. Look for Franklin’s Gulls in mixed flocks of gulls and terns in farm fields and along lake shores.
Little Gull (Rare)

Nonbreeding Little Gull (Andrew Cannizzarro Photo – CC by 2.0)
Identification
The Little Gull is aptly named as it has the distinction of being the smallest gull species in the world. In breeding plumage, This species has a white underside, light gray wings, dark underwings, red legs, a black hood, and a tiny black bill.
In nonbreeding plumage Little Gulls look the same but without a full black hood and instead just a dark spot on the side of the head and black smudging on the top of the head.
Range
Little Gulls are actually more of a Eurasian species than they are a North American Species. Most of the population resides in Europe year round, moving to Northern Europe to breed. In the United States, there is a small breeding population occurs in Canada and around the Great Lakes. This species is rare in most parts of the United States.
Diet and Foraging Behavior
Unlike larger gulls, Little Gulls are more limited by the type of food they can eat simply due to their size. Their diet consists mostly of small fish, insects, and other invertebrates that can be found near water. Little Gulls behave more like terns when foraging, often hovering above the water and swooping in to catch flying insects or to scoop fish from the surface.
Where to Find this Bird
Little Gulls can only be found in a few regions of the United States. They can sometimes be found wintering on the Atlantic Coast, especially in New England. In the Midwest they can be found sparingly on the Great Lakes. Otherwise, these small gulls show up irregularly in most other parts of the continental United States and are a big-time rarity.
Sabines Gull (Rare)

Identification
Sabine’s gulls are a very interesting looking gull species with a white body, gray wings, and a black head. The head is not quite the same as other dark-headed gulls however as it has a darker edge to it looking like it has a ring of black separating the head and neck. The bill of the Sabine’s gull is also unique as it is black with a yellow tip. In flight, Sabine’s gulls show black primaries and white secondaries, making it look like they have two white triangles on their wings along with one large gray triangle.
Juvenile Sabine’s gulls do not have a black heads but rather smudges of grayish brown on their head, neck, and back. In flight, Juvenile Sabine’s gulls show a similar pattern to those of the adults but with the more muted brown tones instead of the gray back of the adults. Additionally, juvenile Sabine’s gulls will show a black stripe on their tail while in flight.
Range
Sabine’s Gulls spend most of their time In the arctic, breeding in Northern Canada and Alaska. During migration, this species moves along the Pacific Coast of the United States. It’s worth noting that Sabine’s gulls are also found in Western Europe. For most people in the continental U. S., the best time to see this species is during fall migration.
Diet and Foraging Behavior
Sabine’s gulls eat insects, small fish, crustaceans, and other aquatic invertebrates. They feed in a variety of places including tide pools, around fishing boats, and in snow drifts. They also feed in a variety of different ways from catching prey mid air, to foraging along the shore and picking through debris to find insects.
Where to Find this Bird
Since Sabine’s Gulls breed in the arctic tundra they are difficult to see most of the year with the exception of migration. For the best chance to see one of these gulls, a pelagic on the west coast is going to give you the best chance. Otherwise, keeping an eye out for them on lakes and rivers during migration can also turn one up.
California Gull (Rare)

Identification
California Gulls look very similar to Herring Gulls with a white body and head, gray wings and back, black wing tips with white spots when folded, and a yellow bill. One big difference between Herrings Gulls and California Gulls is that California Gulls have yellow legs while Herring Gulls have pinkish legs.
Nonbreeding adults look virtually the same but with more streaking on the necked head.
Range
California Gulls winter along the Pacific coast from southern Mexico to Washington state. In summer, California Gulls breed in Southwestern Canada and some of the states in the northwestern U.S. including Montana, North Dakota, Colorado, and northern California. They live year round in states like Idaho and Washington. California Gulls are migratory and will occasionally show up in states in the Midwest and Northeast. However, they are considered rare in most places east of the North and South Dakota.
Diet and Foraging Behavior
California Gulls are omnivorous and eat pretty much anything ranging from fish, to insects, to fruit, to garbage. They forage on land, in the water, and in flight.
Where to Find this Bird
California Gulls can easily be found along the coasts of California, Oregon, and Washington where they are quite common. They can also be seen inland during the spring and summer. Look for California Gulls around lakes and rivers along with more urban environments. Another place California Gulls can be found is at garbage dumps.
Summary
Gulls can be both frustrating and exciting species to find and identify. Tennessee has a fairly wide variety of gulls to find, and we hope that this article helped shed some light on how to find and ID them.
