Gray-headed Canary-Flycatcher
Culicicapa ceylonensis
An unmistakable, dainty woodland flycatcher with a slightly peaked head shape. It has a gray head and upper breast with a narrow white eyering. Upperparts are olive-green; breast and belly are bright yellow. An active member of mixed-species foraging flocks, but also seen singly or in pairs. Quite vocal, with a loud, squeaky whistled song delivered throughout the year: “wi-tu-wi-tu-wee!” or “wi-wuh-wuh-wee!!”. Frequently gives a rapid-fire series of high bouncy notes that rises quickly, then trails off. Other calls include sharp “chilup,” “kitwik,” or “chit” notes repeated a few times.
识别特征
The grey-headed canary-flycatcher is about 12–13 cm (4.7–5.1 in) long with a squarish grey head, a canary yellow belly and yellowish-green upperparts. They forage actively like flycatchers and perches in a very upright posture. The sexes are indistinguishable in plumage. They have a very flat bill (which gave it the earlier genus name of Platyrhynchus) which when seen from above look like an equilateral triangle and is fringed with long rictal bristles.<p>Across their range, populations differ in the shades of the colours and vary slightly in dimensions and several of these have been designated as subspecies. The nominate subspecies breeds in peninsular India in the hills of the Western Ghats, Nilgiris, central India and the Eastern Ghats (Lammasingi) and Sri Lanka. Subspecies calochrysea first described by Harry Oberholser in 1923 breeds along the Himalayas east to Myanmar and Thailand and winters across southern India. The nominate form is darker in shade. Subspecies antioxantha which was also described by Oberholser has a breeding range from southern Burma, Thailand through Malaysia to Java and Bali. The island population sejuncta described by Ernst Hartert in 1897 is found on Sumbawa, Flores and possibly on Lombok while connectens described by Bernhard Rensch in 1931 is restricted to the island of Sumba.<p>The grey-headed canary-flycatcher was earlier considered to be an Old World flycatcher in spite of its odd crest, colours and nature of vocalization. Molecular phylogeny studies however show that they are quite different and have been placed in the family Stenostiridae that is closely related to the tits and penduline-tits.

分布与栖息地
This species breeds in upland to montane oak (Quercus) and other broadleaved forests and similar wooded areas in temperate to tropical southern Asia, from Pakistan, Central India, Bangladesh and Sri Lanka east to Indonesia and southern China. Many populations are resident, but some Himalayan birds are partial migrants that winter in peninsular India sometimes even occurring in arid habitats. Other populations may make altitudinal movements but in parts of the eastern Himalayas such as Bhutan, they have been found to occur all year round, and can be found up to and above 2,000 m ASL. During the non-breeding season, they are seen in the plains and lower elevations (September to March in India) when they prefer well wooded areas of relatively mature secondary forests, abandoned plantations and overgrown gardens, usually near water and streams including wooded gorges. They are very active and noisy throughout the day foraging at all levels of the forest.

行为
The grey-headed canary-flycatcher is an insectivore and like flycatchers makes sallies for aerial insects from a low perch under the canopy of a tree. A pair may forage together and they will often join mixed-species foraging flocks. They breed in summer (April to June in India and possibly later in western China). The nest, built by the female alone, is an unlined cup bound by cobwebs and often attached to and covered by moss. The nest is found placed against the mossy trunk of a tree or built on rocks or on a ledge in a mud bank. The typical clutch is three or four eggs. Hodgson's hawk-cuckoo has been observed parasitizing the brood of this species in northern Borneo.

Brahminy Starling
Sturnia pagodarum
A small fawn-colored starling with a long wispy crest that usually lies limp over the back of its head, but the feathers on its cheek and upper breast stand up and away from its cheek. Its upperparts are gray and the dark tail is tipped in white. Note the yellow bill with a blue base. Often seen in small family groups, feeding on fruits and nectar as well as insects on the ground or in the trees. They have a wide repertoire of calls and are also given to mimicking other species.
Opal-rumped Tanager
Tangara velia
Common tanager, found in a variety of forest habitats. Usually seen from below, in which case it is best identified by uniform dark underparts with rufous lower belly and undertail coverts, and active behavior. The shining white rump can be seen from most angles on perched birds, even when high overhead. Found in tall rainforest, shorter-stature forests on sandy soils, and in disturbed areas. Groups move rapidly through treetops, usually with other species of small tanagers, feeding on fruit. Calls are indistinct chips, often given in rapid series in flight.
Elegant Crescentchest
Melanopareia elegans
A striking little bird, shaped like a robust gnatcatcher. Note the bold black-and-buff head pattern, black chest fading to rufous flanks, and bright rufous on the wings. Tail is long and narrow. Unmistakable if seen well, but compare with Marañon Crescentchest, which has silvery wing edges and more richly-colored underparts. Secretive; singles or pairs skulk in dense thickets and understory of dry woodland and second growth, up to 2,300 m. More often detected by song; listen for a series of loud, popping chip notes.
