The southern yellowthroat (Geothlypis velata) is a species of bird in the family Parulidae, the New World warblers. It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay. The southern yellowthroat was formally described in 1809 with the binomial Sylvia velata, mistakenly classing it with the Old World warblers.
The southern yellowthroat's taxonomy is not yet resolved. Well into the twenty-first century it was treated as a subspecies of the masked yellowthroat (Geothlypis aequinoctialis). In 2015 the IOC recognized it again as a full species and in 2022 the Clements taxonomy followed suit. The initial version of AviList in 2025 also treats it as a species. However, as of late 2025 and early 2026, respectively, BirdLife International's Handbook of the Birds of the World (HBW) and the South American Classification Committee retain it as a subspecies of the masked yellowthroat.
The southern yellowthroat is 13 to 14.3 cm (5.1 to 5.6 in) long and weighs 11 to 17 g (0.39 to 0.60 oz). The species is sexually dimorphic. Adult males have a wide black mask from their forehead and forecrown around the eye and including the ear coverts... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Southern Yellowthroat is recorded against all the birds logged in Buenos Aires (2,311 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.
