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.

Rare
Under 5% of wildlife watchers report a Bay-headed Tanager sighting in Cali on a given day, based on 38 verified sightings from GBIF citizen-science data. It is the 124th most-seen of the 226 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Bay-headed Tanager in Cali on a given day, against under 5% in October to August, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Bay-headed 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.
Among the best
Of the 4 cities where we can rate Bay-headed Tanager sightings, Cali ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Medellín (Colombia, under 5%) and Caracas (Venezuela, under 5%).
GBIF citizen-science records
It is estimated from how often the Bay-headed Tanager is recorded against all the birds logged in Cali (38 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.
