They are small-bodied birds. The smallest, the Short-billed Honeycreeper, is 9 cm long and weighs 9 grams. The longest, the Magpie tanager is 26 cm. The heaviest is the White-capped Tanager which weighs 114 grams. Both sexes are usually the same size and weight. Tanagers are known for being brightly colored. Some species are black and white. Birds in their first year are often more dull in color or a different color altogether.Males are more brightly coloured than females. The two sexes are usually the same size. Most have short, rounded wings. The shape of the bill seems to be linked to the species’ foraging habits.

Habitat
Tanagers are restricted to the New World tropics. About 60% of tanagers live in South America. About 30% of these species live in the Andes.Most species are endemic to a relatively small area. Most tanagers live in pairs or in small groups of 3-5 individuals. These groups may consist simply of parents and their offspring. Birds may also be seen in single species or mixed flocks. Tanagers are thought to have dull songs. Some are very elaborate.
