Jerdon's Leafbird
Chloropsis jerdoni
Crisp emerald-green forest-dweller. Male has a dark blue throat patch outlined by a thick black border. Female has a pale blue throat with no dark border. Only similarly-colored bird in range is the Golden-fronted Leafbird, which has an orange forehead. Jerdon’s Leafbird is a species of lowland and foothill forests, particularly dry open wooded areas and forest edges. Joins mixed-species flocks, particularly at flowering and fruiting trees. Song is an assemblage of harsh squeaks, buzzing notes, whistles, and imitations of other species.
识别特征
Jerdon's leafbird (Chloropsis jerdoni) is a species of leafbird found in forest and woodland in India and Sri Lanka. Its name honours Thomas C. Jerdon. It has traditionally been considered a subspecies of the blue-winged leafbird (C. cochinchinensis), but differ in measurements and morphology, it lacking the blue flight feathers for which the blue-winged leafbird was named. It builds its nest in a tree, and lays 2–3 eggs. This species eats insects, fruit and nectar. The male is green-bodied with a yellow-tinged head, black face and throat. It has a blue moustachial line. The female differs in that it has a greener head and blue throat, and young birds are like the female but without the blue throat patch. Like other leafbirds, the call of Jerdon's leafbird consists of a rich mixture of imitations of the calls of various other species of birds. They are very shy of water, will only come down to drink for very short periods and are quick to flee.

White-backed Duck
Thalassornis leuconotus
A smallish, tawny, bulbous-headed duck that sits low in the water, its tail often flush with the surface, giving it a distinctive appearance. When seen well, the white patch at the base of the bill is diagnostic. The namesake white back is usually visible only in flight. Partially nomadic; small groups are found on pans and pools that have emergent aquatic vegetation, especially waterlilies. Mostly quiet; rarely gives a squeaky-toy-like “swit-swit” whistle.
Yellow-footed Green-Pigeon
Treron phoenicopterus
Brightly-colored pigeon with significant regional variation. Look for a gray “shoulder strap” and yellow legs. South Asian birds are the brightest, with an orange-yellow neck and green underparts. Southeast Asian birds have more extensive gray on the underparts. Sexes are similar. Found in lowland forest and forest edge, as well as parks, gardens, and orchards; a common urban bird in much of its South Asian range. Not extremely vocal; occasionally gives cooing whistles.
Cryptic Becard
Pachyramphus salvini
Small becard occurring from southwest Colombia to northwest Peru, mainly on the west slope of the Andes and in the Marañon drainage, but (perhaps seasonally?) on the east slope of the Andes as well. Mostly found in foothills, in middle to upper levels of humid montane forest, dry forest, and more open second-growth. Male is mostly gray with bold white edges on the wing feathers and a black cap with pale spectacles. Compare with White-winged Becard, which has a black back and dark lores. Female is very different; look for her brown cap bordered with black, white spectacles, pale yellowish belly, and tawny edges on wing feathers. Extremely similar to Black-and-white Becard, with potential range overlap on the east slope of the Andes in Ecuador and Peru. Male Cryptic shows a narrower upper wingbar, paler lores, a grayer upperside of the tail, and a more slender bill than Black-and-white. Female Cryptic has a duller brownish crown with a narrower black border. These features may all be difficult or impossible to assess in the field; some birds are best left unidentified. Also note voice: song a fast series of two sweet downslurred whistles followed by a stuttered upslurred whistle, often repeated two or three times. Black-and-white’s song is slower, with longer notes.
