Chattering Cisticola

Quite nondescript, this small forest bird is brown above and white below. Forages on the ground in wet lowland areas, particularly near rivers and in coastal mangroves. Typically moves in pairs. Similar in appearance to Ferruginous Babbler but is duller, grayer, and more specialized in its habitat preferences. Song is a high, snappy, “wee-wee-ti!”.

A small grayish-brown nightjar with a chestnut neck, back, and central tail. Note the white throat patch and white tips to outer tail and wings in flight. Nocturnal. Found in mangroves and lowland forest edges. The only nightjar on Palau. Most common call is a low, slightly accelerating series of “kew” notes given when perched.

Small leaf warbler with many extremely similar relatives. Like other “Pallas’s-type” leaf warblers, has olive-yellow upperparts, pale underparts, prominent brow and crown stripes, double wingbars, and a pale rump. Unlike Ashy-throated and Buff-barred Warblers, lacks any white on outer tail edges. Pallas’s averages yellower-headed and brighter overall. Gansu and Chinese Leaf Warblers can be incredibly similar, but Lemon-rumped averages whiter-browed and yellower-bellied than the former, more contrastingly-marked on the head than the latter, and darker-billed than both. As with many other physically similar leaf warblers, best distinguished by voice and habitat. Breeds in coniferous and mixed forests at mid- to high-elevation forests, though may descend into foothills in the winter. Two song types are both highly distinctive; one is a buzzy, descending rattling trill and the other is a series of high-pitched clicking twitters. Call is a loud, strident pair of notes: “pse-tew!”
