Cell phone message from Non Birding Bill on the way to catching his bus to work this morning:

The neighborhood Cooper's hawk nailed a pigeon this morning. The flocks on the old folk's home took flight and circled the street. The flock instantly scattered when the Cooper's flew in towards the center and focused on one bird. Both took off back toward's the old folks home, over the roof, the pigeon flew down, the Coop's followed, and then there was a poof of feathers.

I'm sorry I missed that.
