Wagler's toucanet (Aulacorhynchus wagleri) is a species of bird in the toucan family Ramphastidae.

[3] It was long considered one of many subspecies of the then emerald toucanet (Aulacorhynchus prasinus sensu lato).

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 eye is dark reddish brown surrounded by even darker bare skin.

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

[9] Wagler's toucanet is found in the Sierra Madre del Sur of southwestern Mexico's Guerrero and the western part of Oaxaca states.

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.

[1] However, it "is vulnerable to habitat destruction" and "subject to special protection" under Mexican law.
