About the Rondônia Warbling-Antbird

The Rondonia warbling antbird or Rondonia antwarbler, (Hypocnemis ochrogyna) is a Vulnerable species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia and Brazil.

The Rondonia warbling antbird was described by the American ornithologist John T. Zimmer in 1932 as a subspecies of the then warbling antbird Hypocnemis cantator sensu lato. Following a study published in 2007 that assessed vocal differences and to a lesser degree differences in plumages among the warbling antbird's subspecies, it and several others were elevated to full species status. The Rondonia warbling antbird is monotypic.

The Rondonia warbling antbird is 11 to 12 cm (4.3 to 4.7 in) long and weighs 11 to 15 g (0.39 to 0.53 oz). Adult males have a black crown with a white central streak and a white supercilium on an otherwise black and white speckled face. Their upperparts are olive-gray with a white patch between the scapulars; the center of the patch has black and white speckles. Their rump is rufous. Their flight feathers are brown with yellowish olive-brown edges and their wing coverts black with white tips... Wikipedia →
