Shrikes are unique in that they are predatory songbirds with a hooked bill, and cheery call. Nicknamed “Butcher Birds”, shrikes will hang their prey from thorns or barbed wire fences. There are two species of shrikes that can be reliably found in the United States, and they both look similar with a few noticeable differences.
Shrikes of the United States
Loggerhead Shrike
Identification
The Loggerhead Shrike is a gray bird with a thick, black mask, hooked black bill, gray body, clean white stomach, black and white wings, and black tail feathers. They look similar to the Northern Shrikes, but adults will have a thicker black mask and a clean white stomach, as opposed to the barred stomach of the Northern Shrike. Loggerhead Shrikes also have a more head-heavy appearance.
Range
Loggerhead Shrikes can be found year round in many parts of the Southern United States, and move further north in their breeding season; going as far as parts of Southern Canada and into the Northern United States. During their nonbreeding season, some individuals may expand further south into areas where they are not normally found year round.
Diet and Foraging Behavior
Loggerhead Shrikes feed mostly on insects, reptiles, amphibians, small mammals, and birds, but they will also eat organisms that are already dead such as roadkill.
Where to Find this Bird
Look for Loggerhead Shrikes in open areas that also have isolated perching structures such as low trees, shrubs, or fences.
Northern Shrike
Identification
Northern Shrikes look similar to Loggerhead Shrikes, with a gray back, white stomach, black mask, and black and white wings and tail. However, an adult Northern Shrike will have a thinner black mask, and a barred stomach, as opposed to a clean white stomach.
The Northern Shrike has some year-round range in Alaska, but mostly lives in Northern North America in summer and migrates down to the Northern and Central United States in winter.
Diet and Foraging Behavior
Northern Shrikes feed mostly on insects and small vertebrates, but will sometimes also eat carrion. Although they do not have talons, Shrikes will use different tactics to kill their prey, including driving it into the ground or using their hooked bill. Once dead, Shrikes will sometimes wedge the prey onto a thorn or wire.
Where to Find this Bird
Look for Northern Shrikes in boreal forest during the summer, where it opens up with tundra habitat. In winter, Northern Shrikes can be found in edge habitat with open landscape nearby, and ample perches, whether manmade or natural.

Geese can be loud, but also beautiful birds that can be found in Wisconsin. Since there are only a few different species that call the state home, it 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. Most can be seen more frequently in Wisconsin during spring and fall when they migrate.
The geese species below are grouped by those that can be found in Wisconsin annually, those that are vagrants (they occasionally show up), and finally, those that are domesticated escaped birds that can sometimes be found in parks or other urban areas.
Geese that can Annually be Found in Wisconsin (5 Species)
Canada Goose
Identification
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. Due to their ability to live year-round in urban spaces, this species can be seen in Wisconsin year round.
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.
Cackling Goose
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. They can be found in Wisconsin annually, and will normally be seen during the spring and fall, mixed in with flocks of Canada Geese.
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
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. In Wisconsin, they can most reliably be seen in the spring and fall as they migrate.
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
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. In Wisconsin, they can most reliably be seen in the spring and fall as they migrate.
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.
Greater White-fronted Goose
Identification
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. In Wisconsin, they can most reliably be seen in the spring and fall as they migrate.
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.
Geese that Show Up to Wisconsin on Occasion (2 Species)
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 and are a rare visitor to Wisconsin.
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.
Barnacle Goose (Rare)
Identification
The Barnacle Goose can be identified by its white face, black top of the head and neck, gray stomach, and gray, white, and black back.
Range
Barnacle Geese breed in the arctic North Atlantic islands. They are not native to the United States but sometimes they show up as vagrants, especially in the northeastern U.S. and parts of Canada. Additionally, sometimes domesticated birds escape and are seen, therefore there should be some deliberation in considering whether the bird is wild or not. A wild Barnacle Goose would be a very rare visitor to Wisconsin.
Diet and Foraging Behavior
Barnacle Geese feed mostly on vegetation such as grasses and aquatic plants.
Where to Find this Bird
Barnacle Geese are extremely rare in North America. Keep an eye out for this bird in flocks of other goose species, normally found near water or in open grassy areas and farm fields.
Domestic Geese (3 Species)
These species are likely not vagrant birds, but rather domestic pets that have escaped or been released.
Greylag Goose (Domestic)
Identification
Greylag Geese are brown and white with pinkish orange feet and bill. They look similar to Greater White-fronted Geese but are larger, with a striped neck, and a more stout body. Graylag Geese also lack the prominent white forehead seen on the Greater White-fronted Goose.
Range
Greylag Geese are not native to North America, however some domesticated individuals have ended up at parks or urban ponds. They are normally non-migratory and will sometimes even beg for food.
Diet and Foraging Behavior
Greylag Geese feed mostly on grasses and plant material.
Egyptian Goose (Domestic)
Identification
Egyptian Geese are brown, white, and gray with pinkish feet and a spectacled appearance.
Range
Egyptian Geese are not native to North America, however some domesticated individuals have ended up at parks or urban ponds. They are normally non-migratory and will sometimes even beg for food. Egyptian Geese are native to central and southern Africa.
Diet and Foraging Behavior
Egyptian Geese feed mostly on grasses and other plant material such as aquatic vegetation.
Where to Find this Bird
Domesticated Egyptian Geese are not “countable” from a listing perspective in the United States, but can be an interesting bird to see in parks or urban ponds.
Swan Goose (Domestic)
Identification
Swan Geese have a brown back, tan stomach, white stripe down their sides, brown top of head extending down the top of the neck, white and tan side of their neck, pinkish feet, and a black bill. Some birds may also have a knob on their forehead. Swan Geese have also been bred to be all white, and may also be referred to as “Chinese White Geese”.
Range
Swan Geese are not native to North America, however some domesticated individuals have ended up at parks or urban ponds. They are normally non-migratory and will sometimes even beg for food. Swan Geese are native to Asia.
Diet and Foraging Behavior
Swan Geese are thought to be herbivorous and feed mostly on grasses and other plant material such as aquatic vegetation.
Where to Find this Bird
Domesticated Swan Geese are not “countable” from a listing perspective in the United States, but can be an interesting bird to see in parks or urban ponds. Sometimes they associate with domestic Greylag Geese.

Cooper’s vs. Sharp-shinned Hawk is one of the most common identification questions for backyard birders. Adults both have a gray/blue back, long legs, and a banded tail, and juveniles also look similar to each other. However, if you know the identification points to look for, it can be much easier to differentiate the two.
When deciding between a Cooper’s or Sharp-shinned Hawk one of the first things to consider is range. The range of the Cooper’s Hawk spans over more of the United States year round, with Sharp-shinned Hawks spreading out more in the winter. Depending on the time of year, this could narrow down your choices.
Range
Size
First, let’s start with features that apply to adult and juvenile birds. In general, Sharp-shinned Hawks will be smaller than Cooper’s Hawks with the average individual measuring about 12.5 inches, and the average Cooper’s Hawk measuring about 16.5 inches. However, females are larger than males in both species and a large female Sharp-shinned Hawk can be about the same size as a small male Cooper’s Hawk. In general, if the bird seems very small (about Blue-jay size or smaller for Sharp-shinned) or very large (about crow sized or larger for Cooper’s) then then size can be used fairly reliably.
Shape
Another field mark present in both adults and juveniles is body shape and head size. Sharp-shinned Hawks will appear to not have much of a neck, with a small head. Cooper’s Hawks will appear to have normal proportions compared to other hawks. This feature can also be noticed in flight. The general body shape of a Sharp-shinned Hawk will also appear barrel chested with smaller hips, making the bird look top heavy, almost like the Hawk version of Gaston from beauty and the beast. The Cooper’s hawk body shape will be much more tubular with a center of gravity more near the middle of the body.
Legs
In adults and juveniles Sharp-shinned Hawks will appear to have longer thinner legs than Cooper’s Hawks and the eye on the Sharp-shinned may appear closer to the middle of the back and front of the head where in the Cooper’s they may appear closer to the front of the head, although this field mark can be subjective.
Tail
If you get a clear view of the tail this can also assist with ID, although I wouldn’t rely on this as your only field mark. In general, Cooper’s Hawks will have tail feathers that appear more rounded at this tips, while they are more squared off in the Sharp-shinned Hawk. This can be deceiving depending on how spread out the feathers are, and if there are missing feathers. There can also be differences in the amount of white on the tail tip (Cooper’s Hawks will have a broader white tip of the tailfeathers while Sharp-shinned may show a thinner white band) but this can be worn off the feathers which makes it a difficult feature to use reliably.
Flight Pattern
In flight, the Cooper’s Hawk will often fly with slower wingbeats before gliding. Sharp-shinned Hawks may have a more erratic-looking flight with faster wingbeats before gliding.
Hood vs. Cap
Now let’s move on to characteristics of only adult birds. Both Sharp-shinned and Cooper’s Hawks will have gray-blue backs with rufous and white barring on their chests, and red eyes. One of the more distinctive differences in adults is that the Sharp-shinned Hawk will often appear hooded with a dark nape while the Cooper’s Hawk will appear capped, white a light nape.
Neck
Sharp-shinned Hawks may also appear as though they don’t have a neck, while Cooper’s Hawks will normally show a more pronounced neck.
Chest Streaking
Now let’s move on to the juveniles. Juveniles of both species have brown backs with white spots, brown streaks on the chest, and yellow eyes. The most reliable color field mark is that the streaking on the chest is bold and larger in Sharp-shinned Hawks (it may also appear more blurry) and is thinner and more defined in Cooper’s Hawks. The streaking may also not go down as far on the lower stomach in Cooper’s Hawks.
Behavior
There are also some more anecdotal behaviors that have been noted between the species that may be true some of the time but not always. It’s been suggested that Sharp-shinned Hawks prefer to perch in trees and shrubs while Cooper’s Hawks may be found more often on fences or poles. Additionally, Cooper’s Hawks may target larger prey such as does while Sharp-shinned Hawks might go after smaller birds.
Summary
In summary, an adult Sharp-shinned Hawk will normally appear smaller with almost no neck, a broad chest, a hooded head, long thin legs, eyes closer to the middle of the head, and a squared off tail with a thin white tip. In flight they may also appear more erratic. Cooper’s Hawks will generally be larger with a capped head, normal neck, tubular appearance, thicker legs, eyes closer to the beak, and rounded tail feathers with a thicker white band at the end. Their wingbeats in flight may also appear slower. Juvenile Sharp-shinned Hawks will have more streaking on the chest that appears almost blurry, while Cooper’s Hawks will have finer, more defined streaking with possible less on the lower stomach. While you’re out in the field try to note as many ID features as you can and get photos when in doubt. In the end, it’s always okay to mark the bird down as a Cooper’s/Sharp-shinned Hawk. This is a tricky ID, but hopefully with these tips, you’ll be armed with the best knowledge about differentiating these two species.

For many birders and feeder watchers, the identification of House Finches and Purple Finches can be a challenge. While these species do look very similar, when regarding the fine ID points of the two, they can be significantly easier to distinguish.
Range
The first thing to consider when trying to make a positive ID between these two birds is the range. The House Finch has an interesting range with populations in the western United States separated from those in the eastern United States. This species is non migratory and will stick around bird feeders year round.
Unlike the House Finch, the Purple Finch is migratory and spends much of the year in southern Canada with some of them staying year round in California and parts of the midwest and north east. During winter, Purple Finches move into the lower 48 states from the plains states east to the Atlantic Ocean. Just how far this species moves down is dependent on the availability of cone crops in the north and will vary each year.
While there are a few places where it is possible to determine these species based on range, there are many more places where they overlap. This makes range a somewhat unreliable factor to consider.
Shape
When looking at the overall appearance of these two species, there are some size and shape differences that can be helpful to note. House Finches will look slimmer, have a more rounded head, and a more shallow notch in their tail. Also, the upper mandible on the bill of the House Finch is more curved than that of the Purple Finch.
The Purple Finch will look more bulky with a more crested head, and deeper notch on the tail. The bill of the Purple Finch will also look bulkier and the upper mandible will be straighter.
Coloration and Field Markings
While size and shape can be somewhat subjective, the field markings and overall coloration of these two species can be used to make a positive ID with more reliability.
The House Finch has a red, orange, or yellow color on their head and breast. This color does not typically extend to the back and wings. The wing bars of the House Finch are light colored and the underside is streaked with dark brown.
The male Purple Finch will have an rosy-pink or “wine stained” appearance that covers most of its body including the neck and back. They have rosy wing bars as opposed to the light colored wing bars of the House Finch. The Purple Finch will also have less or no dark streaking on their lower stomach.
The females of these two species can also be distinguished with field markings. The female House Finch has little to no marking by the eye as opposed to the female Purple Finch that has a bright eye stripe. The female House Finch will also have a more blurred looking chest and underside while the Purple Finch will have more defined streaking.
Overall
Most birders will encounter one or both of these species at some point, and knowing the fine ID points of each can be instrumental in discerning between them. House Finch males will be slimmer with a rounded head and smaller notch in their tail. Their upper bill will be more curved and they will be red, orange, or yellowish with the color only being on the head or chest. Last but not least, House Finches will have brown streaking on their lower underside. House Finch females will not have a light eye stripe and will have blurred streaking on their chest and underside.
Male Purple Finches will be bulkier with a more crested appearance and a deeper notch in their tail. They will have a thick and straighter looking bill and will be a wine stained color. Their colore will appear to wash over most of the body leading to their wing bars also being rosy looking. A Purple Finch will have little to n dark streaking on their lower underside. Female Purple finches will have a bright eye stripe and defined streaking on their Chet and underside.

Every spring, large flocks of dark-colored, long-necked birds make their way across North America: Double crested Cormorants. Due to their distinctive shape, these birds are easy to identify in the marshes and lakes that they inhabit. However, there is another cormorant species that occasionally makes its way north from central and south America that looks incredibly similar to its double-crested relative: The Neotropic Cormorant.
In most places in the United states, with the exception of some southern states, the Neotropic Cormorant is extremely uncommon. For that reason, it pays to know what to look for in order to find a rare species or simply to differentiate them from Double-crested Cormorants in states where the two species regularly overlap.
Size
The first thing to look at is the size and shape. Neotropic Cormorants are shorter and sleeker than Double-crested Cormorants with an average 61cm height, and a wingspan of 102 cm compared to the 70 to 90 cm height and 114 to 123 cm wingspan of the Double-crested Cormorant. In addition to the basic size difference, the Neotropic Cormorant’s tail will appear longer (compared to its body) than the Double-crested Cormorant’s tail. These characteristics are most noticeable in flight when directly compared to the other cormorant species but can also be seen when the birds are perched.
Lore Color
Size can be difficult to determine without a direct comparison to other nearby birds. Fortunately, there are some other field marks that can be used to distinguish these two species. First, note the lores (just above the bill, going from the eye to the bill) on the Double-crested Cormorant. Both juveniles and adults display yellow to orange colored lores. In Neotropic Cormorant, the lores are significantly darker. When comparing these two next to each other, there is actually a significant difference.
Gular
Another important area to note on these birds is the gular (which is essentially the upper throat). Both species have orange or yellowish gulars, but the shape is different depending on the species. If you look carefully, you can see that the Neotropic Cormorant has a gular that angles toward the bill in an acute angle. The gular on the Double-crested Cormorant angles far less, and in many instances makes a 90 degree angle.
Another field mark birders regularly use to distinguish these species is the white triangular marking that lines the gular on the Neotropic cormorant. It’s very obvious in adults but less visible in juveniles.
Review
It can be really difficult to make a positive ID based on just one characteristic between these two species. For that reason, it’s best to look at all the field markings. As a whole, an adult Neotropic Cormorant will have a smaller, sleeker stature, a longer tail, dark lores, a gular that acutely angles in toward the bill, and a white triangular marking around the gular. An adult Double-crested Cormorant will be larger and blockier, have a shorter, stubbier tale, brightly colored lores, a gular that is less angled near the mouth, and no white triangle mark around the gular.
A Double-crested Cormorant can be identified by regarding these characteristics:
Larger size
Bulkier Appearance
Brightly colored lores

Almost everyone is familiar with the loud and abundant Canada Goose. Even non birders can pick out the familiar brown bodied, black and white faced bird best known for it’s v-shaped migratory pattern and its reputation for being easily irritated by passers by. However, there is another bird closely resembling the Canada Goose that makes its way across North America during migration: The Cackling Goose.
The Cackling Goose looks extremely similar to the Canada Goose. So similar in fact, that it was originally listed as a Canada Goose subspecies. Eventually, it was determined that the Cackling Goose was different enough to warrant its own species distinction. There are now 7 subspecies of Canada Geese and 4 subspecies of Cackling Goose with each subspecies having subtle differences. While at first glance, the two species are tough to tell apart, there are a some diagnostic characteristics that make differentiating the Canada Goose and Cackling Goose much easier.
Size
One of the most noticeable differences between the Canada Goose and Cackling Goose is overall size. The Canada Goose is by far larger with an average length of 76-110 cm and wing span of 127-170 cm compared the Cackling Goose’s much daintier 63-65 cm length and 108-111 cm wingspan. When standing side by side the difference is obvious with the Cackling Goose being closer in size to a Mallard than to a Canada Goose. However, the issue is that a direct comparison is not always possible. In addition, larger subspecies of Cackling Goose can be close to the size of a smaller subspecies of Canada Goose. For this reason, size alone is not always reliable.
Bill
The next distinguishing feature to note is the bill. The Canada Goose’s bill is long and gently sloping to give it a more pointed appearance. The Cackling Goose’s bill is stubbier and slopes down more rapidly; giving it a more triangular appearance. The Cackling Goose’s shorter bill is one of the key features that can be diagnostic in the field even when there are no Canada Geese nearby to compare with.
Neck
Much like bill length, neck length is also a key feature that differs in the two species. The Canada Goose has a comparatively longer neck than the short neck of the Cackling Goose. Even when fully extended, the Cackling Goose will still appear to have a shorter neck. This feature can be slightly deceptive as Canada Geese can appear to have short necks when they are resting and length can be largely dependent of position of the bird..
Other Features
There are a few other less noticeable features that differentiate the species as well. One thing to look for is primary projection. The wing tips of the Canada Goose typically do not stretch as far beyond the rump as those of the cackling Goose. This gives the Cackling Goose a slightly more elegant appearance.
The size and shape of the head can also be used as a diagnostic tool. The Canada Goose’s head is larger and has a more gentle sloped angle from the back of the head to the front. The Cackling Goose has a smaller and more rounded head.

Canada Goose vs. Cackling Goose can certainly be a challenging ID. Since most of the differentiating features are comparative, it can especially difficult to make an identification when there are no other birds around for perspective. With both species varying wildly in size due to many subspecies, no one characteristic should be used to disseminate the two. Instead, all characteristics together can help paint a clearer picture of which birds are Canada Geese and which are Cackling Geese.
