See text The canyon canastero (Asthenes pudibunda) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.

[2] The canyon canastero has three subspecies, the nominate A. p. pudibunda (Sclater, 1874), A. p. neglecta (Cory, 1916), and A. p. grisior (Koepcke, M., 1961).

Adults of the nominate subspecies have a thin buff supercilium and dark brownish lores on an otherwise gray-brown face.

Their chin and upper throat are pale tawny-orange, their lower throat and upper breast light gray-brown with faint paler streaks, their lower breast and belly unstreaked pale gray-brown, and their flanks and undertail coverts dull rufescent brown.

A. p. grisior is found from the Department of Huancavelica in southwestern Peru south into Chile as far as the Tarapacá Region.

The species primarily inhabits rocky areas in arid montane scrublands, often in ravines, and occasionally occurs in Polylepis woodland.

It usually forages singly or in pairs, gleaning prey from low branches and the ground, usually in areas shaded by rocks or bushes.
