Small, creeping bird of highland forest canopy. Chestnut cap, wings, and tail contrast with olive-brown back and gray underparts. At close range, note somewhat decurved bill. Found only in humid highland forests of the tepui region (above 800 m), particularly in areas with heavy growth of mosses and epiphytes. Forages by hitching up large branches and tree trunks, and also creeps along limbs, inspecting bromeliads and bark crevices from which it gleans insect prey. Often encountered with mixed-species flocks. Voice is a long series of high tinkling notes, dropping in pitch and accelerating. No similar species occurs in tepui highlands.
