The brown-capped tyrannulet (Ornithion brunneicapillus) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Colombia, Costa Rica, Ecuador, Panama, and Venezuela and reported for the first time in Nicaragua in 2011.
The brown-capped tyrannulet and the yellow-bellied tyrannulet (O. semiflavum) were for a time considered to be conspecific and now are deemed a superspecies. Both are now monotypic. The brown-capped tyrannulet is about 8 cm (3.1 in) long and weighs about 7 to 8 g (0.25 to 0.28 oz). It is a small flycatcher with a pointed bill. The sexes have the same plumage. Adults have a brownish olive to dark brown crown with a white forehead, lores, and supercilium on an otherwise olive face. Their upperparts are olive. Their wings and tail are dusky olive. Their underparts are bright yellow with faint olive streaks on the breast and flanks. Both sexes have a brown iris, a black bill with an arched maxilla, and dark gray legs and feet. Juveniles have a more olive crown, a less distinct supercilium, paler tips on the wing coverts, and paler yellow underparts than adults. Wikipedia →
