I worked at a zoo in the Vancouver area and was surprised to find that all
of the crow-like birds there were either Northwestern Crows or Common
Ravens- I never saw a single American Crow while I was there. Not sure
where the demarcation line between the two species is, it must be somewhere
in Northern Washington I suppose.
