Moustached Hawk-Cuckoo
Hierococcyx vagans
Large hawk-like cuckoo, dark gray-brown above with streaked underparts and long tail with broad dark bands. Distinctly falcon-like facial pattern distinguishes this species from other hawk-cuckoos. Can be difficult to see, concealed in dense vegetation of lowland and foothill forests and their edges. Vocalizations include a bright two-note “wheup wheup!” and an ascending series of similar notes that abruptly stops after reaching a feverish pitch.

行为
This cuckoo eats insects and small fruits. It has been seen in mixed-species foraging flocks. It is usually found in thick canopy. Males sing at fixed locations in the canopy, its call being chu-chu or kang-koh repeated every two seconds. It also gives a whistling peu peu that becomes hi-hi and then stops. It has been observed parasitising Abbott's babbler and the rufous-winged philentoma. In mainland Southeast Asia, the breeding season is June to August.

Long-billed Spiderhunter
Arachnothera robusta
Well-named: bill is long even for a spiderhunter. Olive-brown above and bright yellow below with faint streaking on the chest. Combination of large size, streaking, an all-dark bill, and yellow belly serve to separate this species from similar spiderhunters in the region. Forages actively in the upper levels of lowland and foothill rainforest. Gives moderately spaced and rather toneless chips.
Short-legged Ground-Roller
Brachypteracias leptosomus
Chunky, elaborately patterned, remarkably short-legged bird. White tail corners are conspicuous in flight. Elusive and uncommon; unlikely to be seen by those not searching for it. Found at low and middle elevations in eastern rainforest. Unlike all the other ground-rollers, spends most of its time in trees, sometimes high in the canopy. Song is a high, short “boop” note that is repeated many times.
Blyth's Swift
Apus leuconyx
A large swift with long pointed wings and a long, deeply forked tail. It has black upperparts, tail, and wings, with a prominent white rump. Feathers of underparts broadly fringed with dirty white, and throat is whitish. Often difficult or nearly impossible to separate in the field from other similar “fork-tailed swifts,” but the white rump band is slightly thinner than that of Pacific Swift, while Salim Ali’s Swift has a slightly differently shaped white throat patch. This species is less blackish than Cook’s Swift, with a slightly wider rump band. Mostly sticks to hills while breeding, but disperses widely post-breeding and large flocks or loose individuals can be seen almost anywhere.
