The brown nunlet (Nonnula brunnea) is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Colombia, Ecuador, and Peru. The brown nunlet is monotypic. Its relationship to others of its genus has not been detailed but it is believed to be most closely related to the rusty-breasted nunlet (N. rubecula) and fulvous-chinned nunlet (N. sclateri) and may form a superspecies with them. It has sometimes been considered conspecific with the latter, and alternatively as conspecific with grey-cheeked nunlet (N. frontalis) and rufous-capped nunlet (N. ruficapilla).
The brown nunlet is 14 to 15 cm (5.5 to 5.9 in) long. Its crown and upperparts are plain brown. It has a buffy rufous band from the bill to the eye, a narrow buffy ring around the eye, and dark grayish brown cheeks. The throat and flanks are dark rufous, and the chin and breast pale rufous.

GBIF citizen-science records
It is estimated from how often the Brown Nunlet is recorded against all the birds logged in Sierra de la Macarena National Park (13 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.
