The black-and-yellow tanager (Chrysothlypis chrysomelas) is a species of bird in the family Thraupidae, the tanagers and allies. It is found in Colombia, Costa Rica, and Panama. The black-and-yellow tanager was formally described in 1869 with the binomial Tachyphonus chrysomelas. By 1912 it had been reassigned to its present genus Chrysothlypis, which it shares with the scarlet-and-white tanager (C. salmoni). Some taxonomic systems incorrectly modified the specific epithet to chrysomelaena, but later restored the original to conform to the International Code of Zoological Nomenclature.
The black-and-yellow tanager is 12 cm (4.7 in) to 13 cm (5.1 in) long. It weighs 11 to 15 g (0.39 to 0.53 oz). It has a thin, sharply pointed bill and resembles a New World warbler. The species is sexually dimorphic. Adult males of the nominate subspecies are mostly bright yellow with a thin black ring around the eye and jet-black hindneck, mantle, upper back, wings, and tail.... Wikipedia →
