The Ancash tapaculo (Scytalopus affinis) is a species of bird in the family Rhinocryptidae. It is endemic to Peru.




Taxonomy and systematics


The Ancash tapaculo was originally described as Scytalopus magellanicus affinis, a subspecies of Magellanic tapaculo. Following a study published in 1997, it was elevated to species rank because of differences in their vocalizations.




Description


The male Ancash tapaculo's head and upper back are gray and the rest of the upper parts dark brown. The underparts are pale gray, and the flanks and vent are buffy with distinct bars. The female is similar but the upper parts are browner. The juvenile's head and upper back are brownish gray and the rest of the upper parts olive brown; all are barred. The underparts are gray, and the flanks and vent are olive brown with dusky bars.




Distribution and habitat


The Ancash tapaculo was described from the Department of Ancash, Peru. Since then it has been recorded in the adjoining departments of La Libertad, Huánuco, and Lima. It is found at elevations of 3,000 to 4,600 m (9,800 to 15,100 ft).
It inhabits tussocky high elevation grassland and rocky areas with grass. It is often found in or near Polylepis woodland or Gynoxys shrubs.
