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.
Pennsylvania 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 (Rare)
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
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.
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.

Range
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
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 (Uncommon)
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.
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.
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.
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.
Diet and Foraging Behavior
Barnacle Geese feed mostly on vegetation such as grasses and aquatic plants.
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.
Pink-footed Goose (Rare)
Identification
The Pink-footed Goose can be identified by its brown head and tan neck, gray-brown back, white side stripe, buff and white chest, white rump, pink feet, and stubby bill.
Range
Pink-footed Geese are not native to the United States but they sometimes stray into Eastern North America. When they do, they are an extreme rarity.
Diet and Foraging Behavior
Pink-footed Geese feed mostly on vegetation such as grasses and sedges.
