The northwestern crow (Corvus brachyrhynchos caurinus) is an all-black passerine bird of the crow genus native to the northwest of North America. It is a subspecies of the American crow (Corvus brachyrhynchos), but it averages slightly smaller (33–41 cm in length) than the nominate subspecies with proportionately smaller feet and a slightly more slender bill. This taxon is perhaps impossible to identify in the field, and is largely identified by range, though even that method is contested.
