Aberdare Cisticola

Wild chickenlike bird. Male is burnt orange with dark streaks, cockerel-like glossy black tail, and a prominent red comb marked with yellow on the crown. Gray-brown female has white streaks and prominent barring on its wings. Terrestrial, found in pairs or small groups in forests of lowlands and highlands over much of Sri Lanka. Generally keeps to cover. Only confusion is with domestic chicken; note lack of white at tail base, and yellow marking on comb of males, and bars in wings of females in Sri Lanka Junglefowl. Song a harsh “chyok-cher-chow”. Also stuttering “kik-kik-kik-kik” notes.

Medium-sized antpitta of floodplain forest, particularly with palmetto understory, along the confluence of the Ríos Madre de Dios and Bení in the Riberalta area. The only antpitta in range with dark chevrons on underparts or a blue-gray cap. Forages on or near the ground, but generally perches 1-2 m up in the understory or midstory to sing at dawn. Visually distinctive in range, but song deceptively similar to, and perhaps indistinguishable from, local songs of Amazonian Antshrike. Call a more distinctive three to four-part descending whistle.

A little-known medium-sized, short-tailed swift found over forest, usually at higher elevations. Mainly black with obvious white throat and underwing patches. Wing shape is unusual, with a “cut-out” next to the body and pointed wing tips curved backward. Tail square, with spines that are difficult to see. Distinguished from other swifts in its range by the white marks under the wings. Voice unknown.
