A species of bird is the Erpornis zantholeuca (white-bellied erpornis) or simply erpornis. It is the only member of the Erpornis genus.

This bird resembles a vireo quite a lot in its coloration, morphology and acrobatic habits. However, like many yuhinas, it has a famous crest, which has worked for a long time along with the peculiar biogeography to conceal its true relationships. This bird's crested head, back, wings and tail are olive or golden brown, while its underparts are white.

Erpornis has well-developed musculature for the forceful gaping or opening of the bill and can do this to pry bark from trees and look for insects.
