Hi centrarchid, I have a Cooper's that visits my yard daily (i just posted in another thread about it) but it doesn't bother my 9 month old chickens. I think they would take smaller ones in a heartbeat though. But speaking of raptor migration, an American Kestrel showed up in my yard yesterday after being absent since about May. I've had one station itself in my yard for the past two winters and it has been great to watch. I got to see it take a sparrow yesterday. I'm guessing that this is the third year for the same bird, but I certainly couldn't tell them apart (and we occasionally get two). I really love to see it take on the Cooper's and, especially, the Red Tailed hawk that will occasionally fly over.
