The wedge-tailed grass finch (Emberizoides herbicola) is a species of bird in the family Thraupidae, the tanagers and allies. It is found in Colombia, Panama, and every mainland South American country except Chile. The wedge-tailed grass finch was formally described in 1817 with the binomial Sylvia herbicola. It was eventually reassigned to its present genus Emberizoides, which was included in a large family of Old and New World species, Emberizidae. A molecular phylogenetic study published in 2014 found that the wedge-tailed grass finch belonged in the tanager family Thraupidae. Some authors have treated the wedge-tailed grass finch and the lesser grass finch (E. ypiranganus) as conspecific and others treated it as conspecific with the Duida grass finch (E. duidae). A 1982 publication confirmed them as three separate species. The three are the only members of the genus Emberizoides.

GBIF citizen-science records
It is estimated from how often the Wedge-tailed Grass-Finch is recorded against all the birds logged in Chapada dos Guimarães National Park (10 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.
