The bluish-grey saltator or Amazonian grey saltator (Saltator coerulescens) is a passerine bird in the tanager family Thraupidae that is widespread in semi-open habitats in tropical and subtropical South America.

The bluish-grey saltator was formally described in 1817 by the French ornithologist Louis Pierre Vieillot under the binomial name Saltator coerulescens. Vieillot based his description on the "Habia de la Ceja Blanca" that Félix de Azara had described in 1802 in his book on birds in Paraguay and the Río de la Plata. The specific epithet coerulescens is derived from Latin and means "bluish".
Saltator coerulescens was formerly known as the greyish saltator and included two subspecies groups: grandis (including brevicaudus, hesperis, plumbiceps, vigorsii and yucatanensis) and olivascens (including brewsteri and plumbeus). In 2021, they were recognized as separate species, the cinnamon-bellied saltator (S. grandis... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blue-gray Saltator is recorded against all the birds logged in Buenos Aires (580 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.
