The brown-headed greenlet (Hylophilus brunneiceps) is a species of bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Brazil, Colombia and Venezuela. The brown-headed greenlet is monotypic. However, what is now the inornata subspecies of the dusky-capped greenlet (Pachysylvia hypoxantha) was previously treated as a subspecies of it.
The brown-headed greenlet is about 11 to 12 cm (4.3 to 4.7 in) long and weighs 8 to 11.5 g (0.28 to 0.41 oz). The sexes have the same plumage. Adults have a brown or dull sepia crown with a slight yellowish wash. Their face is dull brownish. Their upperparts and tail are olive-green. Their wing's primaries and secondaries are dark grayish with thin greenish olive edges on their outer webs. Their throat and upper breast are dirty white with an olive-buff tinge. Their lower breast and belly are gray-white, their flanks yellowish, and their vent pale greenish yellow. They have a gray or whitish iris, a brown maxilla, a pinkish mandible, and pink legs and feet.
The brown-head greenlet is found from eastern Colombia east across most of southern... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brown-headed Greenlet is recorded against all the birds logged in Anavilhanas National Park (23 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.
