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 →

GBIF citizen-science records
It is estimated from how often the Golden-crowned Warbler is recorded against all the birds logged in Maceió (46 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.
