Coscoroba Swan vs Musk Duck

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".
