Gray-capped Flycatcher

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.

A fairly small bird of foothill forest on Waigeo and Batanta islands. Dark blue feet and strange pale blue skin on the top of the head divided by thin, black lines. Male has bottle green chest, red back and yellow on the back of the neck, all or which it can erect into elaborate ornamentation during the display at a court on the ground. Remarkable flattened, curly tail feathers reflect blue. The female is brown above with rufous in the wing and barred below. Unmistakable in range. Male gives a series of loud, downslurred “piuu!” calls, increasing in volume.

Handsome and well-named large babbler with a snow-white “bib.” Also note blue facial skin and bright chestnut back. Crown is brownish on birds from western Java, and grayish on those from central and eastern Java. Despite large size and bright colors, can be quite skulky and difficult to see well. Hops and clambers about in dense bushes and vines in foothill forests, typically in mid-sized groups, giving dry churring rattles. Also gives a short, fluty-sounding whistle.
