Roraiman Antbird

The Roraiman antbird is 14 to 16 cm (5.5 to 6.3 in) long and weighs 24 to 31.7 g (0.85 to 1.1 oz). Males of the nominate subspecies are mostly blackish slate, with wide white tips on their wing coverts. Females have a dark gray crown and dark cinnamon-brown upperparts. Their wings and tail are blackish brown with pale cinnamon-rufous tips on the wing coverts. Their face is gray. Their throat, breast, and belly are chestnut and their flanks and undertail coverts olive-brown. Both sexes have a brown or gray-brown iris and gray to black legs and feet. Males of subspecies M. s. Voice: The Roraiman antbird's song is a "series of slowly starting, accelerating notes, sharply lowered in pitch at end". The species' "long call" is an abrupt high-pitched note followed by a downslurred whistle. Its other calls are apparently the same as those of the spot-winged antbird, an "abrupt unclear note given singly or in series of 2–5" and a "short rattle".
