See text The emerald toucanet (Aulacorhynchus prasinus) is a species of near-passerine bird in the toucan family Ramphastidae.

In 2017 they did split the emerald toucanet into two species, the northern (A. prasinus) and southern (A. albivitta) emerald-toucanets, each with seven subspecies.

Their flanks are bright yellow-green to green-yellow and their undertail coverts and the underside of the tail are chestnut.

The base of their tail's upper surface is green becoming blue towards the end and the tips of the feathers are chestnut.

Subspecies A. p. warneri has a yellowish wash on its throat and some yellow on the face.

Immatures are grayer than adults and the chestnut of the tail tips is browner and smaller.

[9] The subspecies of emerald toucanet are found thus:[9][8] The emerald toucanet primarily inhabits humid montane forest but is also found in more open landscapes like secondary forest, shrublands, pastures, and plantations.

Its diet is eclectic and includes a wide variety of fruits, invertebrates of many orders, and vertebrate prey such as birds, eggs, lizards, and snakes.

They are active and need a large cage for their size, including perches that they can hop back and forth on.

They also require a high-fruit diet, without which they are susceptible to a disease of excessive iron storage that is similar to hemochromatosis in humans.
