The rusty-vented canastero (''Asthenes dorbignyi''), or creamy-breasted canastero, is a species of bird in the family Furnariidae.

Taxonomy and systematics

The rusty-vented canastero was originally described in the genus '' Bathmidura'' (a synonym for ''Pachyramphus''). There are two subspecies of the rusty-vented canastero recognized: ''consobrina'' of southwestern Bolivia, and ''dorbignyi'' of central Bolivia and northwestern Argentina. Many authorities still consider the dark-winged canastero as a subspecies of the rusty-vented canastero. Also, it is possible that rusty-vented canastero is not a member of the genus ''Asthenes'' at all, but instead belongs to the genus ''Phacellodomus''.J. V. Remsen, 2003, Family Furnariidae (Ovenbirds), pages 162-357 in Handbook of the Birds of the World. Volume 8 (J. del Hoyo, A. Elliott, and D. A. Christie, editors). Lynx Edicions, Barcelona
