Yellow-bellied Sunbird-Asity
Neodrepanis hypoxantha
Tiny, round, short-tailed yellow-bellied bird with a thin curved bill. Males are blue on the back and have bright bare skin around the eye in breeding plumage. Rare Madagascar endemic that is found very locally in eastern and northern rainforest at middle and high elevations. Usually in the canopy of stunted forest along ridgelines. Hyperactive nectar feeder that constantly flits from flower to flower. Call is a series of quiet and very high-pitched “tip” notes. Similar to Common Sunbird-Asity, but has brighter yellow underparts and a smaller, less curved bill. Smaller than Souimanga Sunbird, with a thinner bill and shorter tail.
识别特征
The plumage of male yellow-bellied sunbird-asities is very bright, with clean yellow undersides and dark black upper sides with an iridescent blue sheen; the females are duller. The eye is surrounded by a bright blue wattle which derives its colour, like the rest of the asities, from bundles of collagen. The bill is long and decurved, as it is adapted for nectar feeding.

行为
This species is endemic to montane forest above 1600 m on the island of Madagascar. Yellow-bellied sunbird-asities are active nectar feeders. They will aggressively defend a nectar source from rivals of the same species as well as from sunbirds.<p>The yellow-bellied sunbird-asity is listed as vulnerable by BirdLife International and the IUCN. It was once considered to be an endangered species, and even possibly extinct; however, this was due to a lack of ornithological surveys in its high-altitude range. Subsequent research has found it to be more abundant than previously suspected, although it is still considered threatened due to habitat loss and fragmentation.

Malabar Flameback
Chrysocolaptes socialis
A large, crested woodpecker with a golden-olive back endemic to wet lowland and foothill forests in southwestern India. Separated from Common Flameback and other “small-billed” flamebacks by a much larger bill, a mottled black-and-white nape instead of a black nape, and a divided black horizontal stripe below the cheek. Separated from the similarly large-billed White-naped Woodpecker by the less clean-cut face pattern, a red rump, the lack of a clean white nape, and a preference for wetter habitat. A loose participant in mixed-species foraging flocks, often detected by its loud, high-pitched trill similar to that of Common Flameback.
White-headed Duck
Oxyura leucocephala
Remarkable odd-looking diving duck with a long tail, often held cocked. Males have a striking white face and black crown that contrasts with their large blue bill and chestnut body. Female and juveniles have a darker brown bill, more extensive dark crown and pale cheek stripe, similar to Ruddy Ducks. Silent and rarely flies. Rare and local. Usually found in shallow, open water with dense aquatic plants.
Terek Sandpiper
Xenus cinereus
Unique smallish wader with stumpy bright orange legs and a noticeably upturned bill. Plumage gray overall with white belly, but in flight shows conspicuous white trailing edge to wings. Breeds in valley floodplains in tundra and taiga. In the non-breeding season, occurs singly or in flocks in varied wetland habitats, from fresh marshes to tidal mudflats, and often apart from other shorebirds. Feeds by dashing after insects and also by probing bill in mud, like a mini-godwit.
