Андский гусь Oressochen melanopterus

This chunky white-and-black goose is often common and conspicuous on Andean bogs and lakeshores; usually in pairs or small groups and can be confiding in areas where not hunted. Note the small pink bill and pink legs; sexes alike but the male is larger. Local overlap in Andes of central Chile with Upland Goose. Male Upland Geese have a black bill and legs, and dark barring on body. Like the other species in this genus, males give high wheezy whistles whereas females grunt and bray.
