The white-rumped monjita (Xolmis velatus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Paraguay, and as a vagrant to Argentina. The white-rumped monjita was formally described in 1823 as Muscicapa velata, a member of the Old World flycatcher family. It was eventually transferred to genus Xolmis that had been erected in 1826. Because Xolmis is masculine, it was necessary to change the ending of the specific epithet to velatus.
According to the IOC, the South American Classification Committee of the American Ornithological Society (SACC), and the Clements taxonomy, the white-rumped monjita shares genus Xolmis with only the white monjita (X. irupero). However, as of December 2024 BirdLife International's Handbook of the Birds of the World includes six other species in addition to the white-rumped and white monjitas. All agree that the white-rumped monjita is monotypic.
The white-rumped monjita is 19 to 20 cm (7.5 to 7.9 in) long. The sexes have the same plumage. Adults have a mostly white head with a pearly gray nape. Their upperparts are mostly brownish gray with a white rump. The... Wikipedia →

Very likely
About 70% of wildlife watchers report a White-rumped Monjita sighting in Emas National Park on a given day, based on 178 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 187 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
September
In that month about 80% of wildlife watchers report a White-rumped Monjita in Emas National Park on a given day, against about 50% in November, the lowest month. That is one of Emas National Park's driest months, with about 35 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 White-rumped 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 5 parks where we can rate White-rumped Monjita sightings, Emas National Park has the highest daily chance: about 70%. Next come Serra da Canastra National Park (Brazil, about 50%) and Itatiaia National Park (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the White-rumped Monjita is recorded against all the birds logged in Emas National Park (178 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.
