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.

识别特征

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.

迁徙
Vertical migration

行为

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.

Dark Chanting-Goshawk

Dark Chanting-Goshawk

Melierax metabates

A tall, long-tailed, slaty-gray hawk with pink-orange legs and bill base. The flight feathers and wing tips are dark on both the upper and under wings, creating a uniformly dark wing pattern in flight. Pairs inhabit broadleaved woodland and well-wooded savanna. Chanting-goshawks give a strong, gull-like “kleeeu” call, hence their name. Dark Chanting-Goshawk always has a gray-barred rump, while other chanting-goshawks are paler, prefer drier habitats, and have unbarred white rumps. Eastern Chanting-Goshawk has yellow skin at the base of the bill. Pale Chanting-Goshawk has pale inner flight feathers and dark wing tips, creating a very contrasting wing pattern.

Atherton Scrubwren

Atherton Scrubwren

Sericornis keri

Small mostly terrestrial bird of rainforest and wet eucalypt woodlands in a very small range in the Atherton Tabelands of far northern Queensland. Brownish above, grayish yellow below, with long pointed bill, long pinkish legs, and off-white eyering. Forages for insects mostly on the ground or in the lower canopy. Compare Large-billed Scrubwren, which is paler, less likely to feed on the ground, slightly smaller, and has a more twittering call. Song is variable, often including repeated two-note elements.

Black-faced Spoonbill

Black-faced Spoonbill

Platalea minor

Large white waterbird with a long spatula-shaped bill. Breeding adults have long plumes on the head and a smudging of yellow on the chest. The extensive black facial skin distinguishes this species from the Eurasian Spoonbill, the only other spoonbill in range. Often gathers in large flocks, occasionally mixing with Eurasians. Forages in mudflats, estuaries, lakes, and large marshes, sieving out aquatic invertebrates from the water, often in a side-to-side motion.
