The white-bellied erpornis, or simply erpornis, is the only member of its genus. In its colouring, morphology and acrobatic habits it resembles a vireo quite a lot, but has a prominent crest like many yuhinas, which with its unusual biogeography obscured its true relationships for a long time. The crested head, back, wings and tail are olivaceous or golden brown and the underparts white (Wikipedia, general species account).
It has well-developed musculature for gaping, opening the bill forcefully, and may use this to pry bark from trees to seek insects (Wikipedia, general species account).
