Hi Mona and all.
Thanks so much for the information. I will answer Mona at greater length
separately. But I do want to take this chance to reiterate our interest in
information like this about crow roosts around the state, in the context of a
major two year study.
Hopefully soon, but perhaps not in time for this winter, we will have a
reporting website where details of location, size, etc for crow roosts can be
left for us...as well as any negative comments about the effects of roosting
crows. It is in part those "effects" on which the study is focussed.
The url will be www.crowroosts.org.
Thus, if anyone is seeing regular night roosts of hundreds to thousands of
crows anywhere in upstate NY, not just the Basin, I would greatly appreciate
hearing about them. Just drop me an email.
Many thanks,
Anne
