Sunda Warbler

A small, gorgeous swallow with blue-black upperparts, rump, and face, and uniform rich rufous chin, throat and underparts. In flight the underwing coverts are rufous. The juvenile is duller than the adult. Singles or pairs are scarce in grassland and savanna, often associated with the edges of swamps, rivers and partially flooded areas. Similar Red-throated Swallow has a reddish rump and is less rufous below than the much more neatly-plumaged Black-and-Rufous Swallow; other similar swallows are larger with longer tails, red rumps and paler underwing coverts.

A relatively large rosefinch with a heavy, pale bill. The male has a mottled-pink eyebrow and cheeks and dull pink underparts. The female is brownish overall with strong streaking and a pale, lightly streaked supercilium. Best told apart from other similar rosefinches by the combination of large size, large bill, and relatively short wings and tail. Feeds on the ground. Found in high montane regions in conifer forests, or above treeline. In winter, descends to gardens and groves.

A medium-sized cuckoo of lowland and hill forest. Both sexes have a brown body, thick bill, and white stripe below the red eye. Male has distinctive black cap and black facial stripe. Feeds on fruit in the rainforest canopy. Similar to Long-billed Cuckoo, but Dwarf Koel has a shorter, thicker bill and white stripe on the face. Also from the larger female Pacific Koel by the smaller size and plain brown back. Call, a series of rising, single or double whistled notes.
