Chlorophanes spiza

The green honeycreeper is a small bird in the tanager family. It is found in the tropical New World from southern Mexico south to Brazil, and on Trinidad. It is the only member of the genus Chlorophanes. The purplish honeycreeper (Chlorophanes purpurascens), a bird from Venezuela known only from the type specimen, is now thought to be an intergeneric hybrid between the green honeycreeper and either the red-legged honeycreeper or the blue dacnis.
