Cuckoos are slender, medium sized birds, known for being difficult to find. Due to their secretive nature, they can be exciting for birders to see in the wild. In Virginia, there are two species of cuckoos that can be found on an annual basis. Here’s everything you need to know about them.
Black-billed Cuckoo

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 Virginia.
Vultures are large birds of prey that normally have a head or neck that is often devoid of feathers. Due to their habits of feeding on carrion, they have gotten a bad reputation, however their ecological niche is valuable, and they are quite interesting birds. There are two different vulture species that can be found in Tennessee. Here is everything you need to know about those two species.
Turkey Vulture

Identification
The Turkey Vulture is a large brown bird with a pinkish head that is featherless. In flight, the trailing edge of the wings will show white feathers, with the rest of the underside of the bird being brown. Turkey Vulture will often be seen soaring overhead, or perched on cliffs or other tall structures. They can also be seen near roadsides feeding on carrion.
Range
In North America, Turkey Vultures can be seen in southern states and central America year-round. They move into northern states and Southern Canada during the summer. The Turkey Vulture can normally be seen in Delaware during the spring, summer, and fall.
Diet and Foraging Behavior
Turkey Vultures feed mostly on dead prey such as roadkill or carrion. It is said that Turkey Vultures will never attack live prey. They serve as a valuable “clean-up crew” in the ecosystems they inhabit.
Where to Find this Bird
Look for Turkey Vultures soaring overhead or perching up on high structures such as signs, power lines, cliffs, or tall trees. They will often roost or feed in groups. Also keep an eye out for these birds feeding in open areas or roadsides.
Black Vulture in flight (cuatrok77 photo – CC by 2.0)
Identification
Black Vultures look similar to turkey vultures except they have an all black head and appear to have white/gray wingtips when viewed from below, as opposed to white on the trailing wing edge, among other features.
Range
The Black Vulture can be found in many southern and southeastern states in the U.S. as well as in Central America. They are often seen as vagrants in more northern states in the U.S.
Diet and Foraging Behavior
Much like the Turkey Vulture, Black Vultures will feed on roadkill and carrion, often large mammals. However, unlike the Turkey Vulture, they have also been known to eat weak, or dying live prey.
Where to Find this Bird
Black Vultures can be seen soaring overhead, or perched on powerlines, snags, cliffs, or on other tall structures. They can also sometimes be seen in mixed groups of other raptors such as Turkey Vultures.

In the ever-evolving world of birding, eBird has become an imperative tool for both finding and recording bird sightings. This free to use site allows birders to submit checklists of their observations that the site then categorizes and tallies into easy to view displays. The data is also used in many scientific studies to help people understand trends in the world of birds. While eBird has certainly changed the way birders keep track of data, not all checklists are created equal. Although any checklist can be useful to both the observer and anyone looking at it hoping to get information on a sighting, there are some ways to optimize them for future use. Here are 5 ways to make better eBird checklists.
Use Accurate Numbers
The first thing you can do to make better eBird checklists is by using exact numbers when possible. A bad habit that some eBird users have is to catalog species by just putting an x instead of a number. Other than noting a species is present, this does almost nothing in terms of usable data since so much of the questions around bird populations deal with their numbers. A general estimate of the individuals of a species you saw is certainly better than just ignoring the numbers and putting xs, but keeping a perfect record of the numbers is even better. Of course, this is not always possible since flocks of birds are sometimes enormous. For estimating large groups, a good technique to use is grouping. Count the approximate number of birds in one part of the flock and then count how many similar sized groups you see. For getting the exact total one of the easiest ways to do it is by using eBird mobile. With eBird mobile you can add ticks to your bird list in real time and simply save the list to add it to your records. Why is it important to be as accurate as possible? The data from eBird is used to identify trends in bird populations, so the more accurate the date, the better scientists can help species that are in trouble.
Be Specific on Hotspots
When selecting locations on eBird, there are two ways to select the location: Create a personal location or select an existing hotspot. Personal locations are for places like a personal residence or place where a hotspot doesn’t yet exist. Existing Hotspots can be very general and encompass an entire park or be associated with a specific area of the park or wildlife area. However, the problem with selecting general hotspots is that it does little to point other birders in the right direction in what can sometimes be hundreds of square miles of habitat. Furthermore, bird sightings often occur in very specific places such as a tree or bird feeder that the bird tends to frequent. Having a more specific and exact point can be incredibly useful for people looking to re-find the bird, however, eBird reviewers suggest using as specific of a hotspot as you can, and then putting specific details in the comments. Of course, if you’re trying to be intentionally vague then it makes sense not to add specific details in the general hotspot. A person may want to do this to avoid unnecessary stress on sensitive or nesting species, but if it’s a bird that you want others to be able to find, adding those details is more useful.
Add Media
One of the most useful things you can do in an eBird checklist is to add media. EBird accepts both photos and audio clips and oftentimes these things are expected when reporting a rare bird. There are a variety of reasons media is great to add to checklists, one big one is proof that the rare bird seen was correctly identified. What better proof is there than showing the actual images or recordings of the bird in question? Adding media for species that aren’t rare is also useful as each photo or video is added to the Macaulay library (a photo data base) and can be accessed by other birders or downloaded by the original poster. In this way, the photos serve as something of a scrap book of sightings for users that add them.
Add Additional Comments
White-breasted Nuthatch
With each species listed on an eBird checklist, there is a place to input additional comments. For rare birds this is a required field. A lot of times people try to sort of skip over this field by putting limited remarks such as “continuing” which is a personal pet peeve of mine. While yes, it is a little more work to add in comments, it’s actually an opportunity to input information about the sighting. Include a physical description of the bird, but then also where exactly the bird was seen, and what behaviors you’ve noticed about the bird. Additional useful pieces of information such as exact coordinates, if the bird was a flyover, or if the bird was heard only are also extremely useful to add. As I mentioned before, these comments are usually necessary when reporting rarities but adding them for common birds that people may be interested in seeing are also useful.
Add Extra Details
Making a robust description of the bird or birds seen is certainly useful, but adding specific details in the correct location can also be important. EBird comes with some places to enter information such as sex, breeding behavior, and even whether a bird is oiled or not. This information can be entered in just below the general comments and goes to further beef up sightings with useful information.
With eBird becoming an ever-growing part of the hobby, it benefits everyone to have the most accurate data as possible entered into the site. Both for one’s own record keeping, and anyone else who wants to use the information to locate birds or help their populations, making high quality eBird checklists is incredibly useful.

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 Tennessee, plus one more bird that isn’t a cormorant but that looks very much like one. Here is everything you need to know about these 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

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.

Grebes are fascinating birds that look something like a cross between a loon and a duck. These small waterbirds have legs that are at the back of their body which are perfect for diving and maneuvering through the water.
In Pennsylvania, there are five different species of grebes that usually make an appearance on an annual basis, with some of them being extremely common, and others being fairly rare. Here is everything you need to know about these five species.
Eared Grebe (Rare)
Eared Grebes in Breeding Plumage – Photo by Tom Bunker
Eared Grebe Winer Plumage
Identification
Eared Grebes are compact looking members of the grebe family displaying a shorter neck than other species in the grouping as well as a shorter bill. In breeding plumage, this species is quite colorful with a black head, neck, and back, orangey brown colored sides, and golden feathers just behind their bright red eye. It’s also worth noting that they have a crested appearance. In nonbreeding plumage they are far less extravagant looking with a dark head and back, white sides, a white throat, and a white underside. Even in nonbreeding plumage, Eared Grebes still have a bright red eye but they do not appear as crested.
Range
Eared Grebes winter in Mexico and the Southwestern United States in addition to the Pacific coast. In spring, they move north and spend the summer in most of the Northern States west of the Mississippi River as well as Southwestern Canada. They have a habit of showing up farther east than expected during migration.
Diet and Foraging Habits
Eared Grebes eat an assortment of different small vertebrates and invertebrates including fish, shrimp, insects, and amphibians. Since they often live in water with a high salt content, brine shrimp are sometimes a staple food item.
Where to Find This Bird
Eared Grebes are typically found in shallow ponds and lakes. Often times, these birds gather in extremely large groups during migration and are regular visitors of salty bodies of water.
Horned Grebe
Transitional and Breeding Plumage Horned Grebes
Identification
Horned Grebes are fairly small members of the grebe family with a short bill. In breeding plumage, Horned Grebes have a black head and wings with rusty reddish brown sides, a bright red eye, and amber colored feathers near their eye, which somewhat resemble horns. Nonbreeding birds have a black top of the head, wings, and back of the neck, but are white everywhere else. They still have a bright red eye in ninbreeding plumage.
Range
Horned Grebes winter in the Southeastern United States, along the Atlantic Coast, and along the Pacific coast from Baja California all the way up to the Aleutian Islands of Alaska. In spring, they move north and breed in Alaska, Western Canada, and some of the northern states that border Canada such as North Dakota and Montana.
Diet and Foraging Habits
Horned Grebes eat a very wide variety of aquatic creatures including small fish, crustaceans, tadpoles and many different species of insects. They will not only eat aquatic insects but also catch them out of the air.
Where to Find This Bird
Horned Grebes breed in shallow lakes and ponds with plenty of vegetation to hide in. During migration, they show up in many different bodies of water ranging from manmade lakes to ponds.
Pied-billed Grebe

The Pied-billed Grebe is a small and distinctive looking bird with a brown body and white near the tail. The wings and top of the head are darker than the chest and underside. The term “pied-billed” means striped bill, and it’s certainly an apt way to describe the species as the black stripe on the short, wide bill is obvious in breeding adult birds. Nonbreeding birds look generally the same but without as noticeable of a stripe on the bill. One fascinating thing about Pied-billed Grebes is that they can actually control how much of their body is underwater. Sometime they will only have their neck and head above the surface.
Range
Pied-billed Grebes are extremely widespread across the Western Hemisphere with a year-round range in Southern South America, Northern South America, Central America, Mexico, and most of the United States. In summer, Pied-billed Grebes move north and breed in the Northeastern US, as well as the Midwest. They also can be found throughout Southern Canada in summer.
Diet and Foraging Habits
Pied-billed Grebes mostly prey on small fish and crustaceans, but they will also eat snails, tadpoles, and aquatic insects. These birds hunt for food by diving and catching prey items underwater.
Where to Find This Bird
Pied-billed Grebes can be found in slow moving water such as marshes, flooded fields, and ponds.

Identification
Red-necked Grebes are quite striking in breeding plumage when they have their namesake rusty red neck as well as distinctive gray and white cheeks. They also a dark gray to black cap, a long yellow bill with a dark tip, and a dark gray to black back. In nonbreeding plumage, this species is much more pale with only light traces of a red neck and white cheeks. In terms of grebes, the Red-necked Grebe is on the more slender side with a longer neck than many other species.
Range
Red-necked Grebes are widespread across the globe with most of North America, parts of Asia, and Europe serving as a native home to this species. In North America, these birds winter along both the Atlantic and Pacific coasts, then make their way into Alaska and Western Canada (in addition to some states in the continental US) to breed.
Diet and Foraging Habits
Red-necked Grebes eat a variety of aquatic animals, most commonly fish, crustaceans, and insects. They will also eat other aquatic invertebrates as well as reptiles and amphibians. This species takes a page out of the loon handbook when it comes to hunting as they will often use sight to locate food in clear water and then actively hunt for it.
Where to Find This Bird
During the breeding months Red-necked Grebes can be found in marshes and shallow lakes. Usually their breeding areas have thick vegetation lining the shore, providing good places to hide. In winter, the coasts of the United States can hold large numbers of these birds just offshore.
Western Grebe (Rare)
Western Grebe
Identification
Western Grebes are slender looking waterbirds with a longer neck and bill than many other grebe species. They look the same in both breeding and nonbreeding seasons with dark gray to black on their back, wings, back of the neck, and top of the head. They have a white face and underside with a yellow bill and bright red eye.
Range
True to its name, the Western Grebe is a species of Western North America. They winter along the Pacific coast of Mexico and the United States all the way up to the most Southwestern part of Canada. In summer, they move into the Western half of the US and Canada to breed. Western Grebes are year-round residents in parts of Northern and Central Mexico.
Diet and Foraging Habits
Western Grebes primarily feed on fish, but they also eat other creatures found in the water including crustaceans, amphibians, and insects. This species actively dives for it’s prey and easily moves through the water while hunting.
Where to Find This Bird
In winter, look for Western Grebes in saltwater habitats along the Pacific Coast. In summer, this species utilizes large freshwater lakes to breed in.
Summary
Grebes are unique and fascinating waterbirds that don’t quite fit into any other category. 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. Hopefully, this article has helped in answering some questions about the grebes of Pennsylvania.
