Voice has a lot to do with it. I spent a lot of time listening to the small
crows on the beaches of the northwestern Olympic peninsula before I called
them north-western. There is a very distinctive sound to the crows in that
area.

Hi,
What exact criteria do TWEETERS birders use for distinguishing Northwestern
Crows in Washington state? It's a problem that's been bothering me for some
time, and I'd love to know what others think...
Also, are there ebird/ ebird reviewer rules on this?
Cheers,
