Blue-winged Goose

It is a stocky grey-brown goose-like bird about 60–75 centimetres (24–30 in) long with a slightly paler head and upper neck. It has a small black bill and black legs. Standing birds look fairly dull, grey and dirty white, sometimes showing the blue along the edge of the wing. The sexes are similar, but immature birds are duller. The plumage is thick and loose, an adaptation to the cold of the Ethiopian highlands. In flight, the pale blue upper forewing is conspicuous; the primary feathers are black, and the secondary feathers black glossed green. Voice: The blue-winged goose is a quiet species, but both sexes may give a high-pitched whistle; it does not honk or cackle like the true geese, but may make a barking alarm call when flushed.
