Ross’s Geese are pretty similar to Snow Geese, whom they often flock with. They are white all over except for their short, gray-based red-orange bills, short and stubby, pink-red legs and feet, and black wingtips. Both sexes are similar, but the female is slightly smaller.
There is a dark phase variant of Ross’s Goose, but it’s extremely rare. It has a white head, a brownish bill with a red patch, dark gray throats, underparts, and back.
