Sclater's Tyrannulet (Phyllomyias sclateri)


French: Tyranneau de Sclater German: Graubrust-Kleintyrann Spanish: Mosquerito de Sclater

Phyllomyias sclateri


, 1901,

Bueyes, Santa Cruz, Bolivia


Formerly placed in Xanthomyias, along with P. virescens. Suggested to be closely related to P. reiseri on basis of strong similarities in main vocalizations, as well as in general build and posture, and being closer to each other than either is to P. virescens#R. Proposed taxon australis is a synonym. Two subspecies recognized.
