Imeri Warbling Antbird

The Imeri warbling antbird or Imeri antwarbler (Hypocnemis flavescens) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, and Venezuela. == Taxonomy and systematics == The Imeri warbling antbird was described by the English zoologist Philip Sclater in 1865 and given the binomial name Hypocnemis flavescens. It was later merged into 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 Imeri warbling antbird has two subspecies, the nominate H. f. flavescens (Sclater, PL, 1865) and H. f. perflava (Pinto, 1966). == Description == The Imeri 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…
