Emperor Goose
Anser canagicus
The emperor goose has a stout blue-gray body, with spots of black and white, which cause it to have a "scaled appearance". Its head and the back of its neck are white and tinged with amber-yellow; unlike the snow goose, the white does not extend to the front of the neck. The goose is also characterized by a black chin and throat, a white tail, a pink bill, which is tipped with white, and yellow-orange legs and feet. The underside of the emperor goose's wings is gray, unlike the snow goose, which has black and white on the underside of its wings. Voice: Its vocalizations, according to Edward William Nelson, sound like "kla-ha, kla-ha, kla-ha", and can be differentiated from those of other geese by having a more "nasal" sound. It vocalizes less often than other geese, such as the white-fronted goose.

The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange. The upper wing-coverts are dark brown, as in the white-fronted goose (Anser albifrons) and the lesser white-fronted goose (A. erythropus), but differing from these in having narrow white fringes to the feathers.
