A thread on the Northwest Crow in particular are found here:

Before then, on Vancouver Island, bird lists would have Northwestern Crow instead of American Crow. On Vancouver Island, I think it would be generally accepted to put the now subspecies as your ID - realize though after that it is up to community taxon. Of the 47 American Crow observations I have on Vancouver Island, 25 are to RG subspecies. I have many birds identified to subspecies by others in the community, mostly in southern Africa, that as far as I can tell it is by range - I for the most part leave it and let them have at it.
