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.
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 30% of wildlife watchers report a White-browed Warbler sighting in Curitiba on a given day, based on 362 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 247 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a White-browed Warbler in Curitiba on a given day, against about 20% in September to February, the lowest months.
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.
Yes
Of the 6 cities where we can rate White-browed Warbler sightings, Curitiba has the highest daily chance: about 30%. Next come Porto Alegre (Brazil, about 20%) and São Paulo (Brazil, under 5%).
Same family: Parulidae
The closest relatives of the White-browed Warbler that you can see in Curitiba (family Parulidae, New World Warblers) are Tropical Parula (about 30%), Golden-crowned Warbler (about 20%) 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 Curitiba (362 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.
