The black-backed tanager (Stilpnia peruviana) is a bird species in the Thraupidae family. It is endemic to the forests and shrubs of south-eastern Brazil. When first described, it was mistakenly believed that it originates from Peru, leading to the misleading scientific name peruviana. It is closely related to the chestnut-backed tanager, and the two have sometimes been considered conspecific.
It is threatened by habitat loss. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black-backed Tanager is recorded against all the birds logged in Santos (7 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.
