Grauhauben-Papageimeise Suthora zappeyi

Gray head, white eyering, and frequently raised bushy crest set this parrotbill apart from others in its range. Inhabits isolated mountaintop forests, where it forages in small flocks in dense stands of bamboo. Gives low, insect-like trills. Highly restricted in range; found reliably on less than a dozen mountaintops, and unrecorded from valleys and lowlands in between.
