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.

Rare
Under 5% of wildlife watchers report a Blue-and-yellow Tanager sighting in Iberá National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 228th most-seen of the 284 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Blue-and-yellow Tanager in Iberá National Park on a given day, against under 5% in September to July, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Blue-and-yellow Tanager sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 parks where we can rate Blue-and-yellow Tanager sightings, Iberá National Park ranks 4th at under 5%. The best odds are in El Impenetrable National Park (Argentina, about 60%), Lauca National Park (Chile, about 20%) and El Palmar National Park (Argentina, about 20%).
Same family: Thraupidae
The closest relatives of the Blue-and-yellow Tanager that you can see in Iberá National Park (family Thraupidae, Tanagers and Allies) are Brazilian Cardinal (about 70%), Great Pampa-Finch (about 60%) and Sayaca Tanager (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-and-yellow Tanager is recorded against all the birds logged in Iberá National Park (29 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.
