Atlantic black-throated trogon

The Atlantic black-throated trogon (Trogon chrysochloros) is a bird in the trogon family, Trogonidae that is found in southeastern South America.

Details
It breeds in lowlands of eastern and southern Brazil, Paraguay and northeastern Argentina. It has a yellow belly, pale blue eyerings and a yellow bill. Like all trogons, the Atlantic black-throated trogon has distinct sexual dimorphism. The male has a greenish-blue upperpart, while the female has a brown one. It was previously considered conspecific with other black-throated trogons. The species epithet chrysochloros derives from the Greek χρυσος/khrusos means gold, and χλωρος/khlōros means green.

Two subspecies are recognised:


 * T. c. muriciensis Dickens, Bitton, Bravo & Silviera, 2021, northeastern Brazil (Alagoas)
