ashy-headed tyrannulet Tyranniscus cinereiceps

Small, short-billed flycatcher found in the Andes from Venezuela to Peru. Bright yellow below with two pale wingbars. Look for the gray crown, black half-moon-shaped ear patch, and vague olive streaking on breast. Singles or pairs are usually seen foraging at the middle to upper levels of forest and edge, often following mixed-species flocks. Occurs from around 1,000-2,500m.
