The
northwestern crow (
Corvus caurinus) is an all-black
passerine bird of the crow genus native to the northwest of North America. It is very similar to the more western forms of the widespread
American crow (
Corvus brachyrhynchos), but it averages slightly smaller (33–41 cm in length) with proportionately smaller feet and a slightly more slender bill. This
taxon is reliably identified by range only.
