White-plumed Antbird

The white-plumed antbird (Pithys albifrons) is a small species of insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. == Taxonomy == The first formal description of the white-plumed antbird was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae.

Some taxonomists have separated a third subspecies, P. a. brevibarba, from peruvianus but this treatment has found little acceptance. It shares genus Pithys with the white-masked antbird (P. castaneus). Pithys and Phaenostictus are sister genera, and the two may be distinguished by smaller length and weight, shorter tails, and louder songs in Pithys than Phaenostictus. == Description == The white-plumed antbird is 11.5 to 12.5 cm (4.5 to 4.9 in) and weighs 18 to 23 g (0.63 to 0.81 oz). The species is monomorphic, meaning both sexes look the same. Adults of both subspecies have the eponymous white tufts on their forehead and chin. Their crown and the rest of their…
