husa polní Anser fabalis

Rather large, dark gray-brown goose with variable orange patch on bill (often extensively orange, unlike typical Tundra Bean Goose) 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 Tundra Bean-Goose, but Taiga averages a longer, more sloping bill, versus the shorter and thicker bill of Tundra. Breeds in taiga and winters in farmland and wetlands, where it associates readily with other geese.
