The white-rimmed warbler or white-browed warbler (Myiothlypis leucoblephara) is a species of bird in the family Parulidae, the New World warblers.

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.

Rare
Under 5% of wildlife watchers report a White-browed Warbler sighting in Serra da Canastra National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 262nd most-seen of the 294 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the White-browed Warbler is recorded against all the birds logged in Serra da Canastra National Park (9 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.
