About the Unstreaked Tit-Tyrant

The unstreaked tit-tyrant (Uromyias agraphia) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is endemic to Peru. Some late twentieth and early twentieth century authors merged genus Uromyias into Anairetes but by about 2012 Uromyias had been restored. The unstreaked tit-tyrant shares genus Uromyias with the agile tit-tyrant (U. agilis) and the two form a superspecies.

The unstreaked tit-tyrant has three subspecies, the nominate U. a. agraphia (Chapman, 1919), U. a. plengei (Schulenberg & Graham, 1981), and U. a. squamiger (O'Neill & Parker, TA, 1976). The unstreaked tit-tyrant is 12 to 13 cm (4.7 to 5.1 in) long and weighs about 10 g (0.35 oz). The sexes have the same plumage. Adults of the nominate subspecies have a flattish black crest and a long tail. They have a black crown, a gray supercilium with white mottling, and a thin black stripe through the eye on a face that is otherwise gray with some white. Their upperparts are gray-brown with wide but very faint darker streaks. Their wings are fuscous. Their tail is gray-brown with whitish outer edges on the outermost pair of feathers. Their...
