The grey monjita (Nengetus cinereus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, Suriname, and Uruguay. The grey monjita has a complicated taxonomic history. It was formally described in 1816 as Tyrannus cinereus. It was later moved to genus Nengetus that had been erected in 1827. Throughout most of the twentieth century it was assigned to genus Xolmis. Studies published in 2018 and 2020 showed that it should be returned to Nengetus and taxonomic systems began moving it there in 2021. However, as of December 2024 BirdLife International's Handbook of the Birds of the World retained the species in Xolmis. Because the reassignment to Nengetus and other reassignments from Xolmis resulted in species of several genera having the English name "monjita", the South American Classification Committee of the American Ornithological Society is seeking a proposal to consider English name changes.

Likely
About 50% of wildlife watchers report a Grey Monjita sighting in Emas National Park on a given day, based on 121 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 187 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
June
In that month about 70% of wildlife watchers report a Grey Monjita in Emas National Park on a given day, against about 30% in August, the lowest month. That is one of Emas National Park's driest months, with about 10 mm of rain against 190 mm in January. April and December–February have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grey 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.
Yes
Of the 6 parks where we can rate Grey Monjita sightings, Emas National Park has the highest daily chance: about 50%. Next come Serra da Canastra National Park (Brazil, about 30%) and Iberá National Park (Argentina, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Grey Monjita is recorded against all the birds logged in Emas National Park (121 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.
