Andean Goose

The Andean goose is 70 to 76 cm (28 to 30 in) long and weighs 2.73 and 3.64 kg (6.0 and 8.0 lb). Both sexes have the same plumage. Adults' heads and bodies are white. Some scapulars have sooty centers and others are dark brown, giving a striped appearance to the shoulders. The wing's primaries and the tail are black with a greenish gloss. Their bill is coral red with a black nail and the legs and feet are light red. Downy young are mostly white with some blackish spots and streaks. Older immatures are similar to adults but duller. Voice: The Andean goose is very vocal, and males and females have very different voices. Males make "a "soft huit-wit-wit..., crip, quiop, low, grunting kwwwwwu..., single-syllable threat whistle, and double-syllable sexual calls." Females make a louder "somewhat grating kwa-kwak and "a hoarse gack-gack".
