The bay-headed tanager (Tangara gyrola) is a medium-sized passerine bird. This tanager is a resident breeder in Costa Rica, Panama, South America south to Ecuador, Bolivia, and north-western Brazil, and on Trinidad. The bay-headed tanager was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Fringilla gyrola. The specific epithet is a diminutive of the Latin gyrus meaning "ring". Linnaeus based his own description on the "red-headed green-finch" that had been described and illustrated by the English naturalist George Edwards in 1743 in his A Natural History of Uncommon Birds. The type locality is Suriname. The bay-headed tanager is now placed in the genus Tangara that was introduced by the French zoologist Mathurin Jacques Brisson in 1760.

With luck
About 10% of wildlife watchers report a Bay-headed Tanager sighting in Carara National Park on a given day, based on 726 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 172nd most-seen of the 414 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Bay-headed Tanager is recorded against all the birds logged in Carara National Park (726 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.
