The Black-tailed Gnatcatcher (Polioptila melanura) is a very small, active bird with a thin bill, white eye ring, blue-gray upperparts, white underparts, a brownish wash to the wings, and a long, black tail with white outer tail feathers, that is mostly black when viewed from below. The male has black cap. The Black-tailed Gnatcatcher is so small but long-tailed that it is only likely to be confused with other gnatcatchers.
