Northwestern Crow © allaboutbirds.org

May form a superspecies with American Crow (Corvus brachyrhynchos), with which it appears to interbreed in south of range. Genetic swamping of unique features of present species may be accelerated by increasing expansion of American Crow (Corvus brachyrhynchos) facilitated by urbanization and agricultural development of formerly densely forested north-western Pacific coast.
