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 (3341 cm in length) with proportionately smaller feet and a slightly more slender bill. This taxon is reliably identified by range only.

Northwestern Crows (Corvus caurinus) like everyone to know where they are. If they are in the area you'll know it by this well-known "caw". In this case two Crows perform a duet for your listening pleasure. They are wonderful "talkers" and they have lots of variations on the "caw" theme. Listen for the differences in these two, which appeared to be a couple. Northwestern Crows are considered by many experts to be the same species as the American Crow (C. brachyrhynchos), which is somewhat larger, and has a different voice.
