Blue-winged Goose

Cyanochen cyanoptera

A chunky mid-sized goose. Standing bird looks fairly dull, gray and dirty white, sometimes showing blue along the edge of the wing. Flying bird shows pale blue and iridescent green patches in the upperwing and a white patch on the underwing. Found in montane wetlands and adjacent grasslands, often in pairs or small groups, occasionally in large flocks. Less colorful and boldly marked than other similarly-sized waterfowl species. The calls are high-pitched whistles and yelps.

Identification

This is a stocky grey-brown bird about 70 centimetres (28 in) long with a slightly paler head and upper neck. It has a small black bill and black legs. A chunky mid-sized goose. Standing bird looks fairly dull, gray and dirty white, sometimes showing blue along the edge of the wing. In flight, this species shows a pale blue forewing. Sexes are similar, but immature birds are duller. The plumage of these birds is thick and loose, furlike as an adaptation to the cold of the Ethiopian highlands.<p>The blue-winged goose is a quiet species, but both sexes may give a soft whistle; it does not honk or cackle like the true geese.

Range and habitat

The habitats of the blue-winged goose are primarily rivers, freshwater lakes, swamps, freshwater marshes, water storage areas, and subtropical or tropical high-altitude shrubland or grassland.

Migration
Vertical migration

Behavior

It feeds by grazing, and is apparently largely nocturnal, loafing during the day. 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.<p>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.

Other Birds

Inland Thornbill

Inland Thornbill

Acanthiza apicalis

Small bird with thin pointed bill. Upperparts gray-brown, underparts off-white, with dark streaking on throat and breast, reddish-brown rump, white flecking on forecrown, and dark red eye. Often cocks tail upright. Similar Brown Thornbill has brown rather than gray-brown upperparts. Chestnut-rumped and Buff-rumped thornbills both have pale eyes, unstreaked chest, and mostly black tails. Inhabits dry woodland and scrubland, also in wetter habitats in southwestern edges of its range.

Glaucous Gull

Glaucous Gull

Larus hyperboreus

Very large, pale gull. Adults are mostly white with a very pale gray back; note pure white wingtips. Immatures are white or pale tan with light brown markings; also look for the distinctive pink bill with sharply demarcated black tip. Most similar to Iceland Gull but larger, larger-billed, and usually even paler; Iceland typically shows more dark markings on wingtips. Also note shorter wingtips on Glaucous that do not extend far past tip of tail. Breeds in the High Arctic; winters farther south in a variety of habitats, rarely far from a large body of water. Often seen in small numbers mixed with flocks of other large gulls. Hybridizes with Glaucous-winged Gull and Herring Gull in parts of range; hybrids can show any mix of intermediate traits and are sometimes best left unidentified.

Freckle-breasted Woodpecker

Freckle-breasted Woodpecker

Dendrocopos analis

Rather unremarkable and typical-looking small black-and-white woodpecker. Extent of “freckling” on the breast varies; Andaman birds are the most heavily marked, and Indonesian birds the palest. Crown is rose-red in males and black in females. Fulvous-breasted Woodpecker is quite similar, but larger, with a brighter red vent and a more tan-colored breast. Stripe-breasted Woodpecker is also quite similar, but even more brightly-colored below and even larger than Fulvous-beasted. Freckle-breasted inhabits open forest and edge up from lowlands up into foothills and lower montane areas. Gives short, sharp notes and trills.
