Humaita Antbird

The Humaita antbird (Myrmelastes humaythae) is a species of passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Bolivia, and Peru. == Taxonomy and systematics == The Humaita antbird has a complicated taxonomic history. It was described by Carl Eduard Hellmayr as Sclateria schistacea humaythae, a subspecies of the slate-colored antbird (now M. schistaceus). Later authors placed it as a subspecies of the spot-winged antbird (now M. leucostigma), which was successively placed in genera Percnostola and Schistocichla. A 2007 study of the vocal characteristics of the then many subspecies of the spot-winged found significant differences between the taxa. Based on this evidence the Humaita antbird was promoted to species status and given its English name. A 2013 study finalized its move to genus Myrmelastes. The Humaita antbird is monotypic. == Description == The Humaita antbird is 14 to 16 cm (5.5 to 6.3 in) long. Males have medium gray upperparts with an olive-brown tinge. Their wings and tail are blackish gray with wide white tips on the wing coverts. Their throat and underparts are paler gray. Females have a brown crown and upperparts. Their wings and tail are blackish brown with pale cinnamon-rufous…
