Jet antbird

The jet antbird (Cercomacra nigricans) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia, Ecuador, Panama, and Venezuela.

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. Juvenile males are dull brown with narrow white tips on the tail feathers. Subadult males are like adult females with heavier markings.
