Selenidera

Selenidera is a bird genus containing six species of dichromatic toucanets in the toucan family Ramphastidae. They are found in lowland rainforest (below ) in tropical South America with one species in Central America.

All the species have green upper-parts, red undertail-coverts and a patch of bare blue or blue-green skin around the eye. Unlike most other toucans, the sexes are different in colour (sexually dichromatic; hence the name dichromatic toucanets). The males all have a black crown, nape, throat and breast and an orange/yellow auricular streak. The females of most species have the black sections in the male replaced by rich brown and a reduced/absent auricular streak, while the female of one species, the Guianan toucanet, has grey underparts and a rufous nuchal collar, and the female of another, the yellow-eared toucanet, resemble the male except for its brown crown and lack of an auricular streak. The calls are low-pitched and croaking. Most species are relatively small toucans with a total length of , but the yellow-eared toucanet typically has a total length of approx. .
