Rather large, dark gray-brown goose with typically small orange patch on bill, and orange legs. In flight lacks contrasting pale forewing areas of Pink-footed Goose and Graylag Goose. Not always safely told in the field from Taiga Bean Goose, but Tundra averages a shorter and thicker bill, vs. the longer, more sloping bill of Taiga. Breeds on tundra and winters in farmland and wetlands, where it associates readily with other geese.
