The golden-crowned warbler (Basileuterus culicivorus) is a small insectivorous bird in the New World warbler family Parulidae. It has a large geographic range that extends from northeastern Mexico south to northern Argentina. The white-bellied warbler was formerly treated as a separate species but is now considered to be conspecific with the golden-crowned warbler.
The golden-crowned warbler was formally described in 1830 under the binomial name Sylvia culicivora by the German accountant Wilhelm Deppe in a price list of specimens that had been collected in Mexico by Wilhelm's brother Ferdinand Deppe. The specific epithet combines the Latin culex, culicis meaning "midge" and -vorus meaning "eating". The golden-crowned warbler is now one of 12 species placed in the genus Basileuterus that was introduced in 1848 by the German ornithologist Jean Cabanis. The genus name is from Ancient Greek βασιλευτερος/basileuteros meaning "more kingly".
Fourteen subspecies are recognised: Basileuterus culicivorus flavescens Ridgway, 1902 – central west Mexico Basileuterus culicivorus brasierii (Giraud Jr, 1841) – northeast, central east Mexico Basileuterus culicivorus culicivorus (Deppe... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden-crowned Warbler sighting in Parque Estadual Encontro das Águas on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 308 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 Golden-crowned Warbler in Parque Estadual Encontro das Águas on a given day, so our monthly data shows no clear season. January to April have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Golden-crowned 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.
36th of 39
Of the 39 parks where we can rate Golden-crowned Warbler sightings, Parque Estadual Encontro das Águas ranks 36th at under 5%. The best odds are in Itatiaia National Park (Brazil, about 70%), Iguazú National Park (Argentina, about 60%) and Iguaçu National Park (Brazil, about 60%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Golden-crowned Warbler is recorded against all the birds logged in Parque Estadual Encontro das Águas (26 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.
