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 Biotopo Cerro Cahuí on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 128th most-seen of the 191 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Golden-crowned Warbler in Biotopo Cerro Cahuí on a given day, against under 5% in September and November–June, the lowest months. That is one of Biotopo Cerro Cahuí's wettest months, with about 170 mm of rain against 25 mm in March.
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.
29th of 39
Of the 39 parks where we can rate Golden-crowned Warbler sightings, Biotopo Cerro Cahuí ranks 29th 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.
Same family: Parulidae
The closest relatives of the Golden-crowned Warbler that you can see in Biotopo Cerro Cahuí (family Parulidae, New World Warblers) are Magnolia Warbler (about 40%), Black-and-white Warbler (about 40%) and American Redstart (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden-crowned Warbler is recorded against all the birds logged in Biotopo Cerro Cahuí (16 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.
