About Erpornis zantholeuca Blyth, 1844
This bird species, Erpornis zantholeuca, strongly resembles vireos in its coloration, body structure, and acrobatic behavior. It does have a prominent crest, a feature similar to that of many yuhinas. This crest, along with the species' unusual biogeography, kept its true evolutionary relationships unclear for a long time. The bird's crested head, back, wings, and tail are colored olivaceous or golden brown, and its underparts are white. Erpornis zantholeuca has well-developed musculature that lets it gape, or open its bill forcefully. It may use this ability to pry bark off trees to find insects.
