While trimming my house with Christmas lights this afternoon (between 4:00 to 
4:30 PM), a steady stream of crows flew overhead.  They were fairly high up 
and flying toward the south.  My very rough estimate was several thousand 
birds.  I haven't seen so many crows in this area since the pre-West Nile virus 
epidemic.  Anyone know where the roost might be?
