white-browed tit-spinetail Leptasthenura xenothorax

Small, active bird found locally in the southern Peruvian Andes. Brownish gray with a red cap, a white-streaked face, breast, and back, and a white eyebrow. Note its tiny, thumbtack-like bill and its fairly long, pointed tail. Forages in and near Polylepis patches, where it makes quick, short hops through dense bushy vegetation. Its song is a dry, rapid descending trill of chips.
