Black-cheeked Warbler
Basileuterus melanogenys
Small grayish bird with black face, bold white eyebrow, and rufous cap. A clear view of the head should eliminate any confusion with other understory warblers. Sexes alike. Found in pairs or small groups, usually following a mixed-species flock. Stays low. Usually in the forest or at the edge.

Asian Palm Swift
Cypsiurus balasiensis
A small gray-brown swift with long thin wings and a long heavily-forked tail. Darker above and paler below. Can be seen in rapid fluttering flight, often making trilling “tiririree” calls while foraging on insects in pairs or loose flocks. Mostly seen over open areas such as fields and agricultural land, but partial to areas with palms on which they breed.

Tree Pipit
Anthus trivialis
Slender and streaked pipit. Feeds on the ground like other pipits, but perches readily in trees or bushes when singing, or alights in tree at end of parachuting song flight. As the name suggests, usually associated with trees (on breeding grounds), but also found in agricultural areas and grassy scrub in winter. All pipits look rather similar and are best identified to species by combination of habitat and voice: Tree Pipit call a high, shrill, buzzy "tzzz"; song more melodic and varied than Meadow Pipit song.

Large-billed Reed Warbler
Acrocephalus orinus
Poorly known, small gray-brown bird with a large bill, a flat forehead, and a short, pale supercilium. Extremely similar to Blyth’s Reed Warbler, but the Large-billed Reed Warbler has a longer bill, longer legs, and slightly shorter wings. Breeds in damp scrubland at high altitudes. Migratory range and habitats are unclear. Song said to be faster, more complex than that of the Blyth’s Reed Warbler.
