The white-faced nunbird (Hapaloptila castanea) 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 white-faced nunbird is the only member of its genus and has no subspecies. It is not a "true" nunbird (genus Monasa) and is sometimes called the white-face puffbird.
The white-faced nunbird is 23 to 25 cm (9.1 to 9.8 in) long and weighs 75 to 84 g (2.6 to 3.0 oz). It has a large white patch above the bill with a narrow black border at its top. The crown is gray-brown, the mantle and sides of the face dark brown, and the rest of the upperparts including wings and tail an even darker brown. The chin and throat are white and the rest of the underparts bright chestnut. The bill is black, the eye red, and the legs and feet gray. The sexes are essentially the same, with the female perhaps having paler underparts.
The white-faced nunbird is found on the east slope of the Andes from western Colombia through eastern Ecuador into northwestern and central Peru. It inhabits the interior and edges of humid to wet forest and cloudforest... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-faced Nunbird is recorded against all the birds logged in Farallones de Cali National Natural Park (8 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.
