The blue-gray tanager (Thraupis episcopus) is a medium-sized South American songbird of the tanager family, Thraupidae. Its range is from Mexico south to northeast Bolivia and northern Brazil, all of the Amazon Basin, except the very south. It has been introduced to Lima (Peru) and Florida (United States). On Trinidad and Tobago, this bird is called blue jean.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the blue-gray tanager in his Ornithologie based on a specimen collected in Brazil. He used the French name L'evesque and the Latin name Episcopus avis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson in his Ornithologie. One of these was the blue-gray tanager. Linnaeus included a terse description, coined the binomial name Tanagra episcopus, and cited Brisson's work. The specific name episcopus is Latin for "bishop". It was placed in the genus Thraupis... Wikipedia →

Possible
About 30% of wildlife watchers report a Blue-gray Tanager sighting in Sian Ka'an Biosphere Reserve on a given day, based on 690 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 288 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March–May and August–September
In those months about 40% of wildlife watchers report a Blue-gray Tanager in Sian Ka'an Biosphere Reserve on a given day, against about 20% in June, the lowest month.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Blue-gray 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.
36th of 67
Of the 67 parks where we can rate Blue-gray Tanager sightings, Sian Ka'an Biosphere Reserve ranks 36th at about 30%. The best odds are in Poás Volcano National Park (Costa Rica, about 80%), Main Ridge Forest Reserve (Trinidad and Tobago, about 70%) and Chagres National Park (Panama, about 70%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Blue-gray Tanager is recorded against all the birds logged in Sian Ka'an Biosphere Reserve (690 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.
