The black nunbird (Monasa atra) is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. The black nunbird was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle that was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Calculus ater in his catalogue of the Planches Enluminées. The black nunbird is now placed in the genus Monasa that was introduced by the French ornithologist Louis Pierre Vieillot in 1816. The generic name is from the Ancient Greek monas meaning "solitary". The specific epithet atra is from the Latin ater meaning "black".

With luck
About 10% of wildlife watchers report a Black Nunbird sighting in Anavilhanas National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 134th most-seen of the 291 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–July and September–October
In those months about 10% of wildlife watchers report a Black Nunbird in Anavilhanas National Park on a given day, against under 5% in August and November–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black Nunbird 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 Anavilhanas National Park, in our data
Anavilhanas National Park is the only park on Wallace's Line with enough records to rate Black Nunbird sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black Nunbird is recorded against all the birds logged in Anavilhanas National Park (35 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.
