The Blue-winged Goose (Cyanochen cyanopterus) is a large sheldgoose, which is endemic to Ethiopia. It is the only member of the genus Cyanochen.
It breeds by mountain lakes and streams. This little-known species is believed to build a lined nest amongst grass tussocks, and to lay 6-7 eggs. It can swim and fly well, but this terrestrial bird is reluctant to do either, and is quite approachable. It forms flocks outside the breeding season.
The Blue-winged Goose is a stocky 60-75 cm grey-brown bird with a slightly paler head and upper neck. It has a small black bill and black legs. In flight, this species shows a pale blue forewing. Sexes are similar, but immature birds are duller.
The Blue-winged Goose is a quiet species, but both sexes may give a soft whistle. It feeds by grazing, and is apparently largely nocturnal, loafing during the day.* Wildfowl by Madge and Burn, ISBN 0-7470-2201-1
