"Blue-gray Tanager," Wikipedia, the free encyclopedia. The blue-gray tanager 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 1618 cm (6.37.1 in) long and weighs 3040 g (1.11.4 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.
