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 São Paulo on a given day, based on 185 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 353 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-browed Warbler in São Paulo on a given day, so our monthly data shows no clear season.
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.
3rd of 6
Of the 6 cities where we can rate White-browed Warbler sightings, São Paulo ranks 3rd at under 5%. The best odds are in Curitiba (Brazil, about 30%) and Porto Alegre (Brazil, about 20%).

GBIF citizen-science records
It is estimated from how often the White-browed Warbler is recorded against all the birds logged in São Paulo (185 verified sightings), 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.
