Paul,
 Thanks for your post regarding the Cave Swallows. You bring an  insight into 
their migrations (and other strays) that is fresh and informative.  I found 
it very helpful and useful in better understanding their wanderings.  Since 
seeing all these great birds recently, many people have asked me where and  why 
they occur, especially this late in the season, and I can now give them a  
better answer!
