Just went up to OWL to give them a Douglas Squirrel my dog nabbed
yesterday, sad end for a bitchy little yard mascot but a wholesome meal for
one of their 70-odd birds. A rain squall following the cold front had just
gone through, complete w/ a little hail, and even though, like you, I
didn't want to be out in the rain, there were a lot of birds around right
after it moved through. I sat and watched a female COOPER'S HAWK as she
sat drying on a wire across the road, all poofed out and nearly dripping,
plus two male and one female NORTHERN HARRIER, two immature and nine mature
BALD EAGLES. I always have had really good luck right after a system moves
through, especially in my canoe.
