The white-fronted nunbird (Monasa morphoeus) is a species of near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, Panama, Peru, and Venezuela.
The first four subspecies were at one time treated as individual species. Other authors included rikeri in the nominate morpheous. Birds in northeastern Bolivia were suggested as a separate subspecies but remain included in peruana. The white-fronted nunbird, black-fronted nunbird (M. nigrifrons), and black nunbird (M. morphoeus) are generally treated as a superspecies.

Rare
Under 5% of wildlife watchers report a White-fronted Nunbird sighting in Belém on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 126th most-seen of the 144 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June–July and November
In those months about 10% of wildlife watchers report a White-fronted Nunbird in Belém on a given day, against under 5% in August–October and December–May, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-fronted 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 Belém, in our data
Belém is the only city on Wallace's Line with enough records to rate White-fronted Nunbird sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the White-fronted Nunbird is recorded against all the birds logged in Belém (6 verified sightings), 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.
