Rusty-crowned Tit-Spinetail Leptasthenura pileata

Attractive, long-tailed bird found in the high Andes of Peru. Plumage is brown overall with a chestnut crown, speckled throat, and streaked belly. Plumage varies geographically, and birds in southern Peru are much darker below with bolder streaking. Inhabits scrub and woodland with short trees. Vocalizations have a metallic quality; they include a high-pitched trill and a series of sharp chips.
