Tyrant-flycatchers (Tyrannidae)

Brown-capped Tyrannulet (Ornithion brunneicapillus) - HBW 9, p. 274

French: Tyranneau à tête brune German: Braunkappen-Kleintyrann Spanish: Mosquerito Coronipardo

Taxonomy: Tyrannulus brunneicapillus Lawrence, 1862, Isthmus of Panama.
Formerly placed in a separate genus, Microtriccus, together with O. semiflavum. The two form a superspecies; previously considered conspecific, but now split by most authors on basis of plumage, voice and habitat, also no apparent intergradation where ranges come together in Costa Rica. Birds from N Colombia (Santa Marta region) and NW Venezuela described as race dilutum, supposedly slightly paler below on average, but not reliably distinguishable from other populations. Monotypic.

Distribution: Caribbean slope of Costa Rica S to W & N Colombia, W Ecuador, and locally in W & N Venezuela (E to S Miranda).
