The white monjita (Xolmis irupero) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. The white monjita was formally described in 1823 as Tyrannus irupero. It was eventually transferred to genus Xolmis that had been erected in 1826.
According to the IOC, the South American Classification Committee of the American Ornithological Society (SACC), and the Clements taxonomy, the white monjita shares genus Xolmis with only the white-rumped monjita (X. velatus). However, as of December 2024 BirdLife International's Handbook of the Birds of the World includes six other species in addition to the white and white-rumped monjitas.
The white monjita is 17 to 18 cm (6.7 to 7.1 in) long and weighs 21 to 29.5 g (0.74 to 1.0 oz). Adult males of the nominate subspecies are almost entirely white. They have black primaries, primary coverts, and tail tip. Females are almost identical but have a gray tinge on their back. Wikipedia →

With luck
About 10% of wildlife watchers report a White Monjita sighting in El Impenetrable National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 146th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April and October
In those months about 20% of wildlife watchers report a White Monjita in El Impenetrable National Park on a given day, against under 5% in February–March and June–July, the lowest months. December has too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most White Monjita sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate White Monjita sightings, El Impenetrable National Park ranks 3rd at about 10%. The best odds are in Iberá National Park (Argentina, about 40%) and El Palmar National Park (Argentina, about 10%).
Same family: Tyrannidae

GBIF citizen-science records
It is estimated from how often the White Monjita is recorded against all the birds logged in El Impenetrable National Park (23 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.
