Sumatran Drongo
Dicrurus sumatranus
Glossy large-billed drongo with glossy blue-sheened wings and tail. Also note bright red eyes, iridescent speckling around the throat and neck, and flared broad-tipped tail. Endemic to Sumatra, where it is the only regularly-occurring “Hair-crested type” drongo, a group which has undergone extensive taxonomic changes recently; some older field guides may refer to this taxa as either Hair-crested or Spangled Drongo. Inhabits foothill forests, where it often associates with mixed flocks in the upper and middle levels of forest. Can be a source of confusion with other drongos, such as Black, Lesser Racket-tailed, Bronzed, and Crow-billed, but note habitat, distinctive tail shape, and flat-headed profile. Gives a variety of vocalizations, including bright fluty whistles and harsh chattering.

Chestnut-sided Warbler
Setophaga pensylvanica
Breeding birds show yellow cap, black triangle under eye, streaked back and reddish-brown sides. Looks remarkably different in fall with distinctive lime green above and gray below with bold white eyering. Breeds mainly in secondary forests, especially areas with large shrubs and young trees. Does well in disturbed habitats, particularly power line cuts and areas that have been logged. Forages for insects. Winters in Central America.
Yellow-crested Tanager
Loriotus rufiventer
Medium-sized tanager of humid forest canopy. Males are black with a yellow crest, throat, and belly; the yellow belly is easily seen from below and distinguishes it from the similar Flame-crested Tanager. Females are yellowish brown. Individuals and pairs often join mixed-species flocks with other tanagers.
Timor Flowerpecker
Dicaeum hanieli
Small and stout forest-dweller that hops and buzzes about in the canopy like a large, active insect. Note male’s iridescent dark blue back, red chest patch, and black line extending partway down the white belly. As with many other flowerpeckers, the female is considerably duller, with a red rump patch being the only patch of bright color on her otherwise gray-brown plumage. Endemic to Timor, where found in montane and foothill forests. Song is a brief, high-pitched and silvery burst of whistled notes: “tsee’di-lee’see.”
