Trilling Shrike-Babbler
Pteruthius aenobarbus
Adorable stout little yellowish bird of Java’s foothill and montane forests. Male is unique, with bright yellow underparts, flashing black-and-white wingbars, dark lores, and a deep rust-red throat. Female is more nondescript but still fairly distinctive, with cinnamon-and-gray wingbars and a light cinnamon tinge on the forehead and front half of the eyebrow. Both sexes have bright silver eye arcs and a dark line extending through the eye. Like other shrike-babblers, forages at middle and upper levels of forest, sometimes with mixed flocks. Song is a loud and repetitive series of high notes; calls are dry and buzzy.

Common Iora
Aegithina tiphia
Breeding adult males are black above and rich yellow below with white wingbars. In nonbreeding plumage the upperparts are greenish-yellow, but the wings are still black with white wingbars. The female is similar in appearance to a nonbreeding male. These birds are quite vocal and can produce a wide variety of calls. The most commonly heard is the whistle “twiii tuiii twiiii.” Apart from this, it utters variable “chirrs” and chattering. The song is a trilled “wheeeee-tee.” Common Iora are frequently seen in wooded areas, scrub, and cultivated lands.
Gray-headed Kite
Leptodon cayanensis
Scarce hawk of lowland tropical forest. Perches mainly in the canopy, at times giving a long, laughing call. In flight, the wingbeats are loose and floppy. When soaring the wings are held rather level. Adult is distinctive, with a soft gray head, dark eyes (no yellow in the face, unlike most hawks), and rather small grayish feet. Immature has several plumage types, all with 2–3 broad, pale-gray tail bands. One type has a dark brown head and upperparts and whitish underparts with dark streaking; another has a white head and underparts with a small dark cap.
Black-billed Capercaillie
Tetrao urogalloides
A powerfully built terrestrial bird of remote northern Chinese and Siberian taiga. Male massive, with glossy black head and chest, white-spotted brown wings, and fiery red stripe above the eye. Female smaller, with brown head and neck and black-striped body. Male displays with neck stretched upward and broad black tail tilted up and fanned. Males engage in fierce battles on leks during courtship season.
