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.

About the Ross's Goose
Ross's goose is a white goose with black wingtips and a relatively short neck. 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, though this is extremely rare.
