Asian Emerald Cuckoo
Chrysococcyx maculatus
Stunning jewel of a bird, found in dense forests. Males have vivid, electric green upperparts and black-and-white striped underparts. Females similar but have light orange crown and thinly striped face. Slow in its movements, usually found high up in the canopy gleaning insects from foliage. Parasitizes the nests of spiderhunters and sunbirds. Gives a explosive “chew’wit’it!” in flight, as well as high-pitched descending rattles.
Identification
The Asian emerald cuckoo grows to a length of about 18 cm (7 in). The adult male has an iridescent dark green head, upper parts and upper breast, a white lower breast and a green barred belly. Bare skin round the eye is orange and the beak is orange/yellow tipped with black. The adult female has coppery-green upper parts, rusty brown crown and nape and green-barred underparts. Both sexes show a white band on the underwing when in flight. The underparts of the juvenile male lack the white lower breast and are more heavily barred. The voice is a “chweek” uttered while flying, and various whistled twitters.
Taxonomy
The Asian emerald cuckoo was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus maculatus. Gmelin based his description on the "Spotted Curucui" from Ceylon that had been described and illustrated in 1776 by the English naturalist Peter Brown. The Asian emerald cuckoo is now placed together with 12 other species in the genus Chrysococcyx that was introduced in 1826 by the German zoologist Friedrich Boie. The genus name combines the Ancient Greek χρυσος khrusos meaning "gold" with κοκκυξ kokkux "cuckoo". The specific epithet maculatus is from Latin and means "spotted" or "blotched". The species is monotypic: no subspecies are recognised.

Range and habitat
This cuckoo has a breeding range that extends from the Himalayas eastwards to Myanmar, China and northern Thailand. Further south it is a vagrant or migrant in northern India, Sri Lanka, Malaysia and Sumatra; it is not known to breed in these areas. It frequents forests and woodland margins.

Other Birds
Black Crake
Zapornia flavirostra
A small, pudgy, blackish waterbird with reddish eyes, a yellowish bill, and diagnostic pink-red legs. The immature is browner, with duller legs and bill. It scuttles along the edges of swamps and other water bodies, preferring reedbeds and emergent vegetation to forage on, sometimes quite boldly. Like most crakes, it walks tentatively with its head lowered, picking and probing for insects, plant matter, and other food. The distinctive call is an odd, wheezy bubbling and chattering “cheeew-t-t-t-t treeew, t-t-t-t-t-treew”.
Chestnut-bellied Partridge
Arborophila javanica
Brilliantly colored small partridge of montane and foothill forests. Often difficult to see in the gloom and tangle of shaded vegetation, but note slate-gray back and chest, rusty belly, and bright orange-and-black face pattern. Like other Arborophila partridges, typically forages on the forest floor in small groups. Song is a fast and gradually rising series of “whew” notes; when duetting, one bird gives the aforementioned song while its partner gives a slower, lower-pitched “boo-goo, boo-goo, boo-goo.”
Large-billed Leaf Warbler
Phylloscopus magnirostris
Large leaf warbler with two whitish wingbars, dark greenish-gray upperparts, a long and contrasting white eyebrow, and a robust dark bill. Breeds in high-elevation forest across the Himalayas, where it is scarce, to China, where it is more common. Winters in dense tropical forest in South India and Sri Lanka, where its piercing two-note whistled call is a common sound. Conspicuous during migration as it passes slowly through varied habitats, sometimes singing its pleasant breeding song composed of five whistles.
