. The name is often abbreviated in colloquial usage to "pinkfoot" (plural "pinkfeet"). ''Anser'' is the Latin for "goose", and ''brachyrhynchus'' comes from the ancient Greek ''brachus'' "short" and ''rhunchos'' "bill".
It is a medium-sized goose, long, the wingspan , and weighing . It has a short bill, bright pink in the middle with a black base and tip, and pink feet. 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. The species is most closely related to the

It is similar in size to the small ''rossicus'' subspecies of bean goose, but distinctly smaller than the nominate subspecies ''fabalis''. It produces a medley of high-pitched honking calls, being particularly vocal in flight, with large skeins being almost deafening.

The most important single breeding site, at Þjórsárver in Iceland (holding 10,700 pairs in 1970), was only discovered in 1951, by Sir Peter Scott and his team who made an expedition to seek the breeding grounds.

), also on islets in lakes. Three to six eggs are laid in early to mid-May in Iceland, late May in Svalbard, with incubation lasting 26–27 days. On hatching, the goslings accompany the parents on foot to the nearest lake, where they fledge after about 56 days. Southbound migration is from mid-September to early October, and northbound from mid-April to early May.[
