Coscoroba Swan vs Upland Goose

Coscoroba Swan

Coscoroba coscoroba

Huge4.3 kgWetland

The coscoroba swan is a medium-large sized waterfowl, but smaller than the true swans, at 90 to 115 cm (35 to 45 in) long with a wingspan of about 155 cm (61 in). Males weigh 3.8 to 5.4 kg (8.4 to 12 lb) and females 3.1 to 4.5 kg (6.8 to 9.9 lb). Their appearance is considered to be slightly strange, being intermediate between that of geese and true swans. They have completely feathered faces—unusual for true swans—and their feet are located directly under their bodies, enabling the coscoroba swan to walk more efficiently than the "waddling" of most waterfowl. Voice: The coscoroba swan makes an onomatopoeic "cos-cor-oo", usually as a threat to intruders. They also make a "monosyllabic hooting note" as a contact call between mates. Immature birds make "loud chirps and trills".

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.
