Pink-footed Goose

It is a medium-sized goose, 60–75 cm (24–30 in) long, the wingspan 135–170 cm (53–67 in), and weighing 1.8–3.4 kg (4.0–7.5 lb). It has a short bill, bright pink in the middle with a black base and tip, similar in pattern to tundra bean goose but pink where that species is orange, 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.

Nesting is often on cliffs close to glaciers to provide protection from mammalian predators (mainly Arctic fox), also on islets in lakes. Three to five eggs are laid, with incubation lasting 25–28 days. Eggs measure 7–9 cm (2.8–3.5 in) in length and 4.8–5.8 cm (1.9–2.3 in) in width. 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. The diet is almost entirely herbivorous. In summer, they feed on a wide range of tundra plants, both on land and in water. In winter, they graze primarily on oilseed rape, sugar beet, potato, and various grasses; damage to crops can be extensive, though their grazing can also benefit particularly sugar beet and potato farmers by gleaning leaves and roots left behind after the crop is harvested, reducing the transmission of crop diseases from one year to the next.
