Jet Antbird

The jet antbird is 14 to 15.5 cm (5.5 to 6.1 in) long and weighs 15 to 17.5 g (0.53 to 0.62 oz). Adult males are almost entirely black, with white edges on their outer scapulars, a white patch between them, and a hidden white patch under them. Their wing coverts and tail feathers have white tips and their flight feathers have white inner edges. Females are mostly blackish gray, with white in the same places as the male. They also have a whitish ring around the eye, thin white streaks on their throat and breast, and white barring on their lower belly. Voice: The male jet antbird's song is "4 or more pairs of notes, each pair consisting of sharp abrupt note followed by longer burry note" and has been written as "harsh paired 'tch-ker' notes". The species' call is "a harsh note repeated in series" like "chak chak chak chak chak chak".
