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. The belly is buffy rufous. The bill, eye, and feet are dark.

Rare
Under 5% of wildlife watchers report a Brown Nunlet sighting in Yasuní National Park on a given day, based on 47 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 386th most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Brown Nunlet in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Brown Nunlet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Brown Nunlet sightings, Yasuní National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Sierra de la Macarena National Park (Colombia, under 5%).

GBIF citizen-science records
It is estimated from how often the Brown Nunlet is recorded against all the birds logged in Yasuní National Park (47 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.
