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