The black-crowned monjita (Neoxolmis coronatus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, Uruguay, and as a vagrant to Chile and the Falkland Islands.
The black-crowned monjita has a complicated taxonomic history. It was formally described in 1823 as "Tyrannus Coronatus". In 1927 it was moved to genus Xolmis. A 2018 study determined it did not belong in Xolmis and two 2020 studies moved it to genus Nengetus. The South American Classification Committee of the American Ornithological Society (SACC) placed it instead in genus Neoxolmis that had been erected in 1927 for what became the chocolate-vented tyrant (N. rufiventris). The IOC and the Clements taxonomy soon adopted that change. However, as of December 2024 BirdLife International's Handbook of the Birds of the World retained the species in Xolmis. Because the reassignment to Neoxolmis resulted in species of several genera having the English name "monjita", the SACC is seeking a proposal to consider English name changes.
The black-crowned monjita is monotypic. The black-crowned monjita is 20 to 22 cm... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-crowned Monjita sighting in Buenos Aires on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 230th most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-crowned Monjita in Buenos Aires on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-crowned Monjita 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 Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Black-crowned Monjita sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-crowned Monjita is recorded against all the birds logged in Buenos Aires (32 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.
