The Andean Goose (Chloephaga melanoptera) is a member of the duck and the shelduck subfamily Tadorninae.
It is resident around lakes and marshes in the high Andes, usually well above 3000m. It is largely land bound and will avoid swimming except in emergencies.
This heavily built bird sports a tiny pink bill and white plumage except for black in the wings and tail. The female is similar to the male, but is smaller in size.
The Andean Goose is a grazing species, eating various grasses. It nests on the ground in a bare scrape near water, laying 6-10 eggs. It is territorial in the breeding season, but otherwise forms small flocks.
