Seven Colored Tanager

           The tanagers comprise the bird family Thraupidae, in the order Passeriformes. The family has an American distribution.
         
There were traditionally about 240 species of tanagers, but the taxonomic treatment of this family's members is currently in a state of flux. As more of these birds are studied using modern molecular techniques it is expected that some genera may be relocated elsewhere

           Tanagers are small to medium-sized birds. The shortest-bodied species, the White-eared Conebill, is 9 cm (3.8 in) long and weighs 7 grams, barely smaller than the Short-billed Honeycreeper. The longest, the Magpie Tanager is 28 cm (11 in) and weighs 76 grams (2.7 oz). The heaviest is the White-capped Tanager which weighs 114 grams (4 oz) and measures about 24 cm (9.5 in). Both sexes are usually the same size and weight. Tanagers are often brightly colored, but some species are black and white. Birds in their first year are often duller or a different color altogether. Males are typically more brightly coloured than females.
Most tanagers have short, rounded wings. The shape of the bill seems to be linked to the species' foraging habits.
