Upland Goose

Chloephaga picta

Huge2.9 kgGrassland

Upland geese males are similar to other sheldgeese, notably the kelp goose (Chloephaga hybrida) due to their predominantly white plumage, while females resemble the ruddy-headed goose (C. rubidiceps) due to their similarly barred breast plumage. This species is 60–72.5 centimetres (23.6–28.5 in) long. Greater Magellan geese (leucoptera subspecies) are the largest birds of the genus Chloephaga. Males typically weigh 3.5–4.5 kg (7.7–9.9 lbs) and females range from 2.9 to 3.5 kg (6.4–7.7 lbs). Lesser Magellan geese (picta subspecies) males weigh 2.7–3.6 kg (6.0–7.9 lbs) on average and females 2.
