The grey-cheeked nunlet (Nonnula frontalis) is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Colombia and Panama. The grey-cheeked nunlet was first described by P.L. Sclater in 1854 in Colombia. The nominate has been suggested to constitute more than one taxon based on differences in coloration observed in specimens. N. f. pallescens has occasionally been suggested to be a subspecies of the rufous-capped nunlet (N. ruficapilla) of southern Amazonia. The grey-cheeked nunlet forms a superspecies with the rufous-capped nunlet and the chestnut-headed nunlet (N. amaurocephala), which is restricted to a small area in northwest Brazil. It has been suggested to be conspecific with the rufous-capped nunlet and also with the brown nunlet (N. brunnea).
The grey-cheeked nunlet is 14 to 15 cm (5.5 to 5.9 in) long and weighs 14.5 to 19.5 g (0.51 to 0.69 oz). The nominate subspecies has a very dark chestnut crown and plain brown upperparts, lighter on the rump. Most of the face... Wikipedia →

With luck
About 10% of wildlife watchers report a Gray-cheeked Nunlet sighting in Darién National Park on a given day, based on 32 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 214th most-seen of the 397 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April, September and November–January
In those months about 10% of wildlife watchers report a Gray-cheeked Nunlet in Darién National Park on a given day, against under 5% in February, May–August and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Gray-cheeked Nunlet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Darién National Park, in our data
Darién National Park is the only park on Wallace's Line with enough records to rate Gray-cheeked Nunlet sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Bucconidae
The closest relatives of the Gray-cheeked Nunlet that you can see in Darién National Park (family Bucconidae, Puffbirds) are White-fronted Nunbird (about 20%), Pied Puffbird (about 20%) and White-whiskered Puffbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-cheeked Nunlet is recorded against all the birds logged in Darién National Park (32 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.
