The blue-and-yellow tanager (Rauenia bonariensis) is a species of bird in the tanager family Thraupidae. It is found in Argentina, Uruguay, Brazil, Paraguay, Bolivia, extreme northern border of Chile, and Andean Peru and Ecuador. Some southern region birds migrate northeastwards in the austral winter into eastern Bolivia and northeastern Argentina; also Paraguay where the birds are only migratory non-breeding residents.
Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.
This species was formerly placed in the genus Thraupis. It was moved to Pipraeidea based on the results of a molecular phylogenetic study published in 2014. It was moved to Rauenia based on the study published in 2020. It is monotypic in that genus.

GBIF citizen-science records
It is estimated from how often the Blue-and-yellow Tanager is recorded against all the birds logged in Buenos Aires (1,446 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.
