It is the smallest of the three white geese that breed in North America. It is similar in appearance to a white-phase snow goose, but about 40% smaller. Other differences from the snow goose are that the bill is smaller in proportion to its body and lacks "black lips". Like snow geese, Ross's geese may exhibit a darker "blue" phase or morph ...
This form is a very contrastingly black and white bird, with a uniformly dark sooty-brown back, similarly coloured underparts (with the dark colour extending furthest back of the three forms) and a prominent white flank patch; it also has larger white neck patches, forming a near-complete collar.
The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America , migrating to more southerly coasts in winter, and as resident birds in the Hawaiian Islands .
The snow goose has two color plumage morphs, white (snow) or gray/blue (blue), thus the common description as "snows" and "blues". White-morph birds are white except for black wing tips, but blue-morph geese have bluish-gray plumage replacing the white except on the head, neck and tail tip.
The greater white-fronted goose (Anser albifrons) is a species of goose, closely related to the smaller lesser white-fronted goose (A. erythropus). [2] The greater white-fronted goose is migratory , breeding in northern Canada , Alaska , Greenland and Russia, and winters farther south in North America, Europe and Asia. [ 1 ]
The barnacle goose (Branta leucopsis) is a species of goose that belongs to the genus Branta of black geese, which contains species with largely black plumage, distinguishing them from the grey Anser species. Despite its superficial similarity to the brant goose, genetic analysis has shown it is an eastern derivative of the cackling goose lineage.
It appears in two varieties: the grey-brown, with colouring similar to that of the wild swan goose (Anser cygnoides), and the white. [10]: 371 The bill and the knob are black in the grey-brown variety, and orange in the white; the shanks and feet are always orange. [4]: 361 In birds bred for showing the neck is long and slender.

A domestic goose is a goose that humans have domesticated and kept for their meat, eggs, or down feathers, or as companion animals. Domestic geese have been derived through selective breeding from the wild greylag goose ( Anser anser domesticus ) and swan goose ( Anser cygnoides domesticus ).
