Yellow-breasted warbling antbird (Hypocnemis subflava)

The yellow-breasted warbling antbird is a species of bird in the family Thamnophilidae. Until recently, it was considered a subspecies of ''Hypocnemis cantator'', but based on vocal differences and to a lesser degree differences in plumages it has been recommended treating them as separate species. As presently defined, the yellow-breasted warbling antbird includes a single subspecies, ''collinsi''.
