My son has worked in Alaska for the past 4 summers out of Petersburg, which 
is about 100 miles south of Juneau.   I forwarded him this discussion and 
this is his response.

"This is not anything new.  As long as I've worked for the forest service 
I've been aware of that.  There is a poster in the office with some contact 
information.  I've also seen a lot of northwestern crows, murders of them 
flock together in the hundreds sometimes, and they are fairly prevalent 
around town and knocking off and eating the suet in my backyard.  Never seen 
one of the deformities, but of course Alaska is a big state, and saying 
"coastal Alaska" is sort of like saying in a cornfield in the Midwest.
