Fairly active, medium-sized woodcreeper of pine, pine-oak, and evergreen forest in highlands. Usually found in ones or twos, often traveling with mixed-species feeding flocks of tanagers, orioles, warblers, and others. Creeps up trunks and smaller branches, often poking into epiphytes. Note the slender, slightly curved bill, fine creamy dots on the crown, and creamy streaking on underparts. Calls are thin, reedy whistles, given infrequently.
