Re: [cayugabirds-l] Question on American Crow roost

2015-02-21 Thread Anne Clark
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

 areas east of the roost in Washington county where you can see for quite a 
 way, I often see crows heading in the general direction of this roost late in 
 the afternoon, but I may be 10 miles from the roost.  I am curious as to how 
 far these birds will travel to a roost.  Is there any data on this?  Is there 
 a way to scientifically gather data - that is, possibly having observers at 
 set distances in several directions to count birds when they are moving?  It 
 appears that some birds are moving in the direction of the roost in 
 mid-afternoon and others much later, so I am thinking it may be difficult to 
 get a handle on what is really happening.
  
 Any thoughts?
