The white-rimmed warbler or white-browed warbler (Myiothlypis leucoblephara) is a species of bird in the family Parulidae, the New World warblers. It is found in Argentina, Brazil, Paraguay, and Uruguay. The white-rimmed warbler was formally described in 1817 with the binomial Sylvia leucoblephara. For a time it and a few other species were placed in genus Phaeothlypis and also in Basileuterus. By 2012 the IOC had assigned it to Myiothlypis. BirdLife International's Handbook of the Birds of the World (HBW) did so in 2016.
The white-rimmed warbler's further taxonomy is unsettled. This article follows the majority two-subspecies model. The white-rimmed warbler is about 14.5 cm (5.7 in) long and weighs 14 to 21 g (0.49 to 0.74 oz). The sexes have the same plumage. Adults of the nominate subspecies have a

Possible
About 20% of wildlife watchers report a White-browed Warbler sighting in El Impenetrable National Park on a given day, based on 52 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May, July and September–October
In those months about 30% of wildlife watchers report a White-browed Warbler in El Impenetrable National Park on a given day, against about 10% in January–April, June, August and November, the lowest months. December has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-browed Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 parks where we can rate White-browed Warbler sightings, El Impenetrable National Park ranks 4th at about 20%. The best odds are in Itatiaia National Park (Brazil, about 40%), El Palmar National Park (Argentina, about 40%) and Iberá National Park (Argentina, about 20%).
Same family: Parulidae
The closest relatives of the White-browed Warbler that you can see in El Impenetrable National Park (family Parulidae, New World Warblers) are Tropical Parula (about 30%) and Southern Yellowthroat (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-browed Warbler is recorded against all the birds logged in El Impenetrable National Park (52 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.
