The grey-capped tyrannulet (Phyllomyias griseocapilla) is a Least Concern species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is endemic to Brazil. The grey-capped tyrannulet was originally described as Phyllomyias griseocapilla. It was moved to genus Oreotriccus in the early twentieth century, and Oreotriccus was then merged into Phyllomyias following a 1977 publication.
The grey-capped tyrannulet is monotypic. The grey-capped tyrannulet is about 11 cm (4.3 in) long. The sexes have the same plumage. Adults have a slate-gray crown and nape and bright olive-green back and rump. Their lores and eye area are white with a faint dusky stripe through their eye. Their lower face is pale gray. Their wings are dusky with bright yellow edges on the flight feathers and the ends of the coverts; the latter show as two wing bars. Their tail is dusky olive. Their throat is grayish white, their breast pale gray, their flanks bright yellow-green, and their belly whitish. They have a brown iris, a small and rounded blackish bill, and gray legs and feet.

GBIF citizen-science records
It is estimated from how often the Gray-capped Tyrannulet is recorded against all the birds logged in Itatiaia National Park (593 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
