Sivun Corvus caurinus kuva

Kuvaus:

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.
