I observed a group of 6 American Crows near the intersection of Copper Gulch Rd 
and Reed Rd (Fremont County), this last weekend while at our property, picking 
at the roofing material of an old trailer. They were pulling small things off 
and tossing it around, not eating it or flying off with any of it. It was 
getting hot out and I did not see that they appeared to be feeding on anything 
underneath - they did this for about 15 minutes until a raven flew over and 
sent them flying off. 
 
I also had been forwarded an email earlier in the spring about what appears to 
be raven trouble (not sure of county location):
 
 We have a problem at the cabin with crows/ravens.  I think it's ravens because 
they are so big.  During the winter, we saw that pieces of the screen from two 
small east facing windows in the loft were being torn.  I thought it was some 
critters needing screen for their nests.  But then some neighbors saw the birds 
ramming the windows and tearing out the screens.  They even took a video of it 
for us.  The screens are now totally gone, and the windows are filthy.  We went 
to the cabin yesterday and spent the night - which we haven't done in a long 
time.  A terrible racket woke me up this morning about 5:30.  I thought it 
might be a bear on the deck, but the dogs weren't barking.  It was those darn 
birds attacking the windows! 

Now, I do not know if the above mentioned windows being "attacked" were the 
screenless ones, or if these windows still had screens in them.  
 
Any ideas on what may be driving the behaviors of these Corvids?  I noticed the 
roof vents on my own trailer look like I can see some daylight through them, 
but I am not sure whether the crows are the culprits or just UV and age; but 
would appreciate strategies to protect the new ones I plan to put on if the 
crows visit.  

Please respond off list. 
 
Thanks,
