Learn how to identify the different types of geese, their migration patterns, habits, and more
Geese are a group of waterfowl that are generally larger than ducks but smaller than swans. Geese can be found across the world, and in North America there are nine species that regularly occur. Some, like the Canada goose, can be found throughout the United States, while others like the emperor goose and Hawaiian goose can only be found in certain states. Geese can be found near water when swimming and resting, but often prefer feeding on land in open areas such as fields. Geese are familiar birds, and their loudly honking or squawking flocks are a common sight during spring and fall.
Cackling geese resemble Canada geese in appearance. Male cackling geese are slightly larger than females, with both sexes having long, black necks with white chinstraps. The breast, abdomen and flanks range in coloring from a light gray to a dark chocolate brown, either blending into the black neck or being separated from it by a wide white collar. The back and scapulars are darker brown, the rump is blackish and the tail is blackish-brown with a U-shaped white band on the rump. The bill, legs and feet are black.
Cackling geese are a small-bodied group of four subspecies, consisting of the Aleutian, Cackling, Taverner's and Richardson's geese. Cackling geese have proportionally smaller, stubbier, triangular-shaped bills than their Canada goose counterparts.
In North America, two subspecies of brant are recognized, mostly due to differences in plumage characteristics. Atlantic or Pacific (black) brant are separated into subpopulations inhabiting distinct ranges and having genetic variation. Brant are small, dark geese that have large wings, which give them their characteristic strong flight.
Brant have short necks, small heads and bills. All subspecies have a black head, bill, breast, primaries, tail and legs. The otherwise black neck has a series of white striations, called a necklace, near the middle. The color of the belly varies according to subspecies and subpopulation. Both sexes are identical in plumage, except that the male's white necklace is larger than the female's.
Barnacle geese have a black chest, neck and crown, with a cream-white face. The sexes are similar in appearance, but males typically are larger. The extension of black from the neck over the head gives the face a hooded appearance. The upper back is black, shading posterior to silver-gray. The breast, sides and flanks are a pale gray and the belly, undertail coverts and rump are white, contrasting markedly with the large black tail. The bill, legs and feet are black.
Both sexes of Canada geese have a black head and neck except for broad white cheek patches extending from the throat to the rear of the eye. The female of a breeding pair is often smaller. The breast, abdomen and flanks range in coloring from a light gray to a dark chocolate brown, either blending into the black neck or being separated from it by a white collar. The back and scapulars are darker brown, the rump is blackish and the tail is blackish-brown with a U-shaped white band on the rump. The bill, legs and feet are black. Most subspecies are uniformly large and pale and exhibit the characteristic "honking" call.
There are 7 recognized subspecies of Canada geese: Atlantic, Hudson Bay or Interior, Giant, Moffitt's or Great Basin, Lesser, Dusky and Vancouver. In general, the subspecies nesting farther north are smaller in size and darker in color to the west. The Giant Canada goose is the largest goose in the world, with some individuals weighing more than 20 pounds. They can also be long-lived, with a banded Canada goose at 33 years currently holding the 2nd oldest longevity record for all North American waterfowl.
Male and female emperor geese have gray body plumage that is subtly barred with black and white. The white head and hindneck, which are often stained orange-red from feeding in tidal ponds where iron oxide is concentrated, contrast markedly with the dark foreneck. Contrast distinguishes this goose from the blue-morph snow goose, whose entire foreneck and chin are white like the head. The emperor goose's short bill is pink and lacks the black "grinning patch" present in blue geese. The legs and feet of the emperor goose are yellow-orange, while those of the blue goose are pink.
Hawaiian geese have a black face and crown and cream-colored cheeks. The neck is pale grayish streaked with black and has a narrow dark ring at the base. The body plumage and folded wings are gray-brown with transverse barring. The bill, legs and feet are black and the iris is dark brown. Both sexes are similar in appearance, but males typically are larger.
Ross' geese are the smallest of the three varieties of white geese that breed in North America. The Ross' goose is a small white goose with black primary feathers. The bill is a deep reddish-pink with a paler nail and a variably bluish warty area over the base of the basal area. The legs and feet are rose-pink and the iris is dark brown. The sexes are dimorphic, with the female being 6 percent smaller than the male. The Ross' goose has a relatively short neck and lacks the black "grinning patch" that is typical of greater and lesser snow geese, for which it is often mistaken. Ross' geese may be distinguished from snow geese by their smaller size, more rapid wing beat and higher-pitched call.
The greater snow goose is a slightly larger version of the white-phase lesser snow goose. No color dimorphism has been discovered in this race. In the field it is virtually impossible to tell these two apart. In the hand, the larger size and longer bill of the greater snow goose distinguish it from its smaller counterpart. The sexes are similar in appearance, but the female is often smaller.
Lesser snow geese have two color phases: a dark (blue) plumage and a white (snow) plumage. The two color phases are variations within the same race and do not indicate separate races. The sexes are similar in appearance in both phases, but the female is often smaller. Lesser snow geese can hybridize with Ross' geese, which are similar in appearance. They have pinkish bills with black grinning patches, and the feet and legs are reddish-pink. In the dark phase they have white heads and upper necks, with bluish-gray bodies. In the white phase they are completely white except for black wing tips. The head can be stained rusty brown from minerals in the soil where they feed. They are very vocal and can often be heard from more than a mile away.
The Greater white-fronted goose is named for the distinctive white band found at the base of bill. The sexes are similar in appearance, but males typically are larger. The head, neck and upper back of white-fronted geese are grayish-brown. The lower back and rump are dark brown, and the tail is dark brown and edged with white. The chest and breast are grayish with dark brown to black blotches and bars on the breast, giving it the nickname "specklebelly." The belly and upper and lower coverts are white. The bill is pinkish and the legs and feet are orange. Greater white-fronted geese are a long-lived species, with one individual holding the current longevity record for North American waterfowl at 34 years and 7 months.
