Tyrant-flycatchers (Tyrannidae)

Red-billed Tyrannulet (Zimmerius cinereicapilla) - HBW 9, p. 296

French: Tyranneau à bec rouge German: Purpurschnabel-Kleintyrann Spanish: Mosquerito Piquirrojo

Taxonomy: Phyllomyias cinereicapilla Cabanis, 1873, Monterico, Ayacucho, Peru.
Despite superficial resemblance to Phyllomyias, genus appears to be more closely related to Phylloscartes. This species was formerly placed in a separate genus, Tyranniscus, but exhibits plumage and morphological features (wing pattern, proportionally long tail and bill, and derived characters of both syrinx and palate) typical of present genus. Monotypic.

Distribution: Locally in E Andean foothills in NC & SE Ecuador (W Napo, Zamora-Chinchipe), NC, C & SE Peru (Amazonas, San Martín, Junín and Ayacucho S to Cuzco and Madre de Dios) and N Bolivia (La Paz).
