Black-headed Antbird

The black-headed antbird is 13 to 15.5 cm (5.1 to 6.1 in) long and weighs 21 to 32 g (0.74 to 1.1 oz). Adult males of the nominate subspecies P. r. rufifrons are mostly gray, with black crown, short crest, and throat. Their wings and tail are blackish gray with white tips on their wing coverts and gray underwing coverts. Adult females have a black crown and grayish olive-brown upperparts, wings, and tail. Their flight feathers have thin rufous edges and their wing coverts are black with pale cinnamon-rufous tips. Voice: The black-headed antbird's song in Brazil is a "high, calm, decelerating series of loud sharp 'tieew' notes". It is described as "a loud, whistled pa, peer-peer-peer-peer-peer-pear-pear" in Venezuela and in Peru as "a moderate-paced series of monotone whistles with a stuttered, higher-pitched introductory whistle: hee'hee hew hew hew hew".
