northwestern crows, reifel bird sanctuary

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 is slightly smaller (33-41 cm in length) and has proportionately smaller feet with a slightly more slender bill. It is the calls that are significantly different and often serve to identify it.
