Anser canagicus
The Emperor Goose (Anser canagicus) is a strikingly beautiful and distinctive waterfowl species, instantly recognizable by its unique plumage. Adults sport a pristine white head and nape, sharply contrasted by a black chin and throat, and a body of blue-gray finely barred with black and white, giving it a scaly appearance. Their bill is pinkish-blue, and their legs are bright orange. Averaging 66-89 cm (26-35 in) in length with a wingspan of 119-142 cm (47-56 in) and weighing 2.5-3 kg (5.5-6....
Found primarily along coastal areas of the subarctic, Emperor Geese inhabit low-lying coastal tundra, tidal flats, lagoons, and rocky shorelines. They prefer areas with shallow brackish or saltwater for foraging and elevated hummocks for nesting.
Their diet consists predominantly of marine vegetation, particularly various species of sea lettuce (Ulva lactuca) and eelgrass (Zostera marina), which they glean from intertidal zones. They also consume some terrestrial grasses, sedges, and berries, especially during the breeding season.
Emperor Geese are primarily diurnal, spending their days foraging and typically roosting on water bodies or safe coastal land at night. Their foraging strategy involves grazing on terrestrial vegetation, grubbing for roots and tubers, and dabbling in shallow waters for marine algae and invertebra...
The Emperor Goose has a highly restricted circumpolar breeding range primarily along the Bering Sea coastlines. The vast majority breed on the Yukon-Kuskokwim Delta in western Alaska, with smaller breeding populations found along the coast of Chukotka in northeastern Russia. During fall migration...
