Yellow-browed antbird

The yellow-browed antbird, or yellow-browed antwarbler, (Hypocnemis hypoxantha) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, and Peru.

The yellow-browed antbird is 11 to 13 cm (4.3 to 5.1 in) long and weighs 10 to 13 g (0.35 to 0.46 oz). Adult males of the nominate subspecies have a black crown with white spots down its center. They have a bright lemon yellow supercilium and ear coverts, a black line through the eye, and a black malar "moustache". Their upperparts, sides, flanks, and tail are light grayish olive. Their flight feathers are grayish olive with white tips and their wing coverts black with white tips. Their throat and underparts are bright lemon yellow with some black streaks on the side of the breast. Adult females are similar to males but are overall paler and their crown center and wing covert tips are light buff. Subspecies H. h. ochraceiventris is larger than the nominate. It is overall somewhat browner, with paler yellow underparts, more streaking on the breast, and pale ochraceous buff flanks. Both sexes of both subspecies have a brown iris, a black maxilla, and gray legs and feet. Males have a black mandible and females a gray one.
