Green Cochoa
Cochoa viridis
A gorgeously colored but highly elusive and uncommon bird found in extensive hill forests, particularly in areas with well-shaded ravines, gullies, and streams. Slow-moving and restricted to the canopy, where it blends in with the foliage. If seen, the green body is most obvious, followed by the black and silvery-blue bands on the wing. A better look would reveal a sky-blue head with a thin black eye-stripe and a pale blue tail. Listen for its song, a high, thin, even-sounding whistle, often given repeatedly but difficult to pin down.
识别特征
This Himalayan thrush is moss green. The male has a blue crown, blue wings and tail with a broad black band on the tail. The female has a more greenish body with some rusty spots on the wing coverts. The secondaries and tertiaries have the base of the outer webs yellowish brown with very narrow blue edging, unlike in the male. In some plumages there is a white collar on the sides of the neck. This form was once described as a new species Cochoa rothschildi. First year birds have dark shaft streaks on the body feathers.

分布与栖息地
The green cochoa is found in Cambodia, China, India, Laos, Myanmar, Nepal, Thailand, Vietnam, and possibly Bhutan. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. They make seasonal movements that are not well understood. Their distribution in winter in India is unclear as the species is found only in summer. An old record from Uttaranchal (Nainital) is the westernmost record, and no recent records exist from Nepal. Most records are east of northwest Bengal.

行为
The green cochoa is usually seen in pairs or small groups sitting in tall trees. They usually feed close to the ground, on mollusks, insects and berries. They sometimes launch aerial sallies to capture insects. This species breeds in summer, and the nest is much like that of the purple cochoa, but is usually placed close to water. Both parents take turns incubating. The song is a thin and clear feeeee that dies away. Calls include a short high-pitched pok and harsh notes.<p>The glossy eggs are ellipsoidal and densely speckled.

Narina Trogon
Apaloderma narina
A spectacular, mostly iridescent-metallic-green bird, with a scarlet belly, broad yellow bill, and white under tail. The face and throat of the male are green, while the females’ are dirty gray-brown. It sits upright and still in the canopy of riverine and lowland forest, watching for insect prey, then flying fast and directly to catch it. During the breeding season, its soft, deep, throaty “huooo-huooo” call makes it much easier to find. The similar Bare-cheeked Trogon differs by having a face with a large bare yellow skin patches that extend from cheek to bill--not small blue-green spots. Bar-tailed Trogon has a heavily-barred undertail and prefers montane forest above 900 m.
Black-spotted Barbet
Capito niger
Medium-sized sluggish bird of rainforest canopy. From below note size and sharply demarcated red throat on both sexes. Also occurs in secondary forests and overgrown plantations, sometimes in urban areas. Often seen in pairs at fruiting trees or with mixed-species flocks. Forages slowly and deliberately, feeding on fruit and insects. Often-heard call is a low-pitched, doubled hoot, repeated in series.
Greater Scaup
Aythya marila
Round-headed diving duck. Males have black breast, medium gray back, white sides, and yellow eye. Head appears black with a greenish sheen in good lighting, never purplish. Females are brown overall, grayer on body in winter, with white patch at base of bill and yellow eye. Very similar to Lesser Scaup; note smoothly rounded head without tall peak, puffier cheeks, more extensive white stripe on wing in flight, and larger, broader bill. Can be similar to immature male and female Tufted Duck, but note smoothly rounded head and more extensive white bill base patch in females. Often in flocks with other Aythya ducks. Tends to prefer saltwater bays and coves, but also found in freshwater.
