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.
