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 →

Rare
Under 5% of wildlife watchers report a Blue-gray Tanager sighting in Ría Lagartos Biosphere Reserve on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 176th most-seen of the 216 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Blue-gray Tanager in Ría Lagartos Biosphere Reserve on a given day, so our monthly data shows no clear season.
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.
66th of 67
Of the 67 parks where we can rate Blue-gray Tanager sightings, Ría Lagartos Biosphere Reserve ranks 66th at under 5%. 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 Ría Lagartos Biosphere Reserve (12 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.
