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). On Trinidad and Tobago, this bird is called blue jean.
The blue-gray tanager is 16–18 cm (6.3–7.1 in) long and weighs 30–40 g (1.1–1.4 oz). Adults have a light bluish head and underparts, with darker blue upperparts and a shoulder patch colored a different hue of blue. The bill is short and quite thick. Sexes are similar, but the immature is much duller in plumage.
The song is a squeaky twittering, interspersed with tseee and tsuup call notes.
There are 13–15 commonly recognized subspecies, differing according to the exact hue of blue of the shoulder patch versus the rest of the plumage; they may be greyish, greenish or purplish-blue, with a lavender, dark blue or whitish shoulder patch. For example, T. e. berlepschi (endemic to Tobago) is a brighter and darker blue on the rump and shoulder, T. e. neosophilus with a violet shoulder patch occurs in northern Venezuela, Trinidad, eastern Colombia and the far north of Brazil, T. e. mediana of the southern Amazon basin has a white wing patch, and T. e. cana in the northern Amazon has blue shoulders.
The breeding habitat is open woodland, cultivated areas and gardens. The blue-gray tanager lives mainly on fruit, but will also take some nectar and insects. This is a common, restless, noisy and confiding species, usually found in pairs, but sometimes small groups. It thrives around human habitation, and will take some cultivated fruit like papayas (Carica papaya).
