オオユミハシオニキバシリ Drymotoxeres pucheranii

Bulky woodcreeper with a stout, deeply curved bill. Very rare in tall, wet Andean cloud forest. Brown with buffy streaks on head, neck, and underparts. Dual white stripes on face and thicker bill distinguish it from Brown-billed Scythebill. Usually found alone, sometimes with mixed-species flocks; probes for insects while creeping along moss-covered trunks and branches. Gives a variety of nasal, whiny-sounding squeaks.
