Пестроспинная колючехвостка Leptasthenura striata

Fairly common on western slopes of the Andes and in interior valleys, favoring drier habitats with weedy brush on rocky slopes, and also agricultural areas with hedges and thickets. Often in pairs, foraging low in weedy brush, where can be hard to see well; agile and often active, clinging upside down at tips of branches. Identified by boldly streaked crown and back, weakly patterned or mostly plain underparts, and very long spiky-tipped tail. Compare with the bulkier Andean Tit-Spinetail (local overlap in Peru).
