Andean Tit-Spinetail is a small furnariid of montane northwestern South America. Found in the Andes from western Venezuela south to western Bolivia, it inhabits scrub vegetation and low woodlands from 3000 to 4500 meters in elevation. The species is dark gray brown above and pale brown below, with white streaks on the back, neck, face, and underparts, a white supercilium, and a black-streaked, rufous crown. Tit-like, the species moves around constantly, hanging from low vegetation and makes short, high-pitched contact calls. Andean Tit-Spinetail has a complicated ecological relationship with its congeners in Peru and Bolivia that isn’t fully resolved yet. Five subspecies currently are recognized, varying slightly in plumage coloration.
