The body is mid-grey-brown, the head and neck a richer, darker brown, the rump and vent white, and the tail grey with a broad white tip. The upper wing-coverts are of a somewhat similar pale bluish-grey as in the greylag goose, and the flight feathers blackish-grey.

Ross's Goose
Anser rossii
Ross's goose has a rounded head above a short neck. The bill is short and triangular and has a bluish base with warty structures that increase in prominence with age. Adults are identified by all-white secondary feathers, while juveniles' are dark centered. Females average 6% smaller than males. Legs begin as olive gray on goslings and turn deep red as they mature.No geographic variation or identified subspecies is known. Related species include other Anser geese, particularly the lesser snow goose, where the two mtDNA lineages imply frequent hybridization.
