I've spent a lot of time on the coastal strip where Northwestern crows
predominate (years of flying floatplanes to a lot of spots on the BC coast
plus growing up on the Peninsula and fishing at Sekiu and Neah Bay). Hence
my identification. It's one of habitat and range for me, and while there
are undoubtedly some hybrids, the NW Crows are smaller, fly differently and
are more melodic, if that's the right word, in their singing. They don't
seem to be all that different, but there are a lot of closely related
species like that.

Of course, very occasionally I have been known to make a mistake in
identification. Shocking, but true.
