Guianan Warbling Antbird
Hypocnemis cantator
The Guianan warbling antbird is 11 to 12 cm (4.3 to 4.7 in) long and weighs 10 to 14 g (0.35 to 0.49 oz). Adult males have a black crown with a white central streak and a white supercilium on an otherwise black and white speckled face. Their upperparts are olive-gray with a white patch between the scapulars; the center of the patch has black and white speckles. Their rump is rufous. Their flight feathers are brown with yellowish olive-brown edges and their wing coverts black with white tips. Their tail is brown with pale buff tips to the feathers. Their throat is very pale gray. Voice: The male Guianan warbling antbird's song is "a series of clear notes ... that become raspy rather abruptly, ... accelerating and comprising a short initial note, then 2–6 notes of similar shape and peak frequency, but at a lower peak frequency than the short first note, before an abrupt shift to a third group of 1–4 similar notes at an even higher peak frequency than the initial note".

Their upperparts are grayish brown with a white patch between the scapulars and much black and white speckling. Their rump is rufous. Their flight feathers are brown with yellowish olive-brown edges and their wing coverts black with white tips. Their tail is brown with pale buff tips to the feathers.

Voice: The male Peruvian warbling antbird's song is "not at all warbling...a raspy, almost snarling 'peér, peer-peer-peer-peer-pur-pur-pyur' with descending effect". Females reply with a "shorter, higher-pitched version" that may start during the male's song. Both sexes give "wur-cheeé or wur-cheeé-cheeé" calls.
