The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Turdus griseus in his catalogue of the Planches Enluminées. The southern white-fringed antwren is now placed in the genus Formicivora that was introduced by the English naturalist William Swainson in 1824. The generic name combines the Latin words formica for "ant" and -vorus "eating" from vorare "to devour". The specific epithet grisea... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Southern White-fringed Antwren is recorded against all the birds logged in Salvador (14 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.
