Yes, I think I have found a good patch. And the funny thing is it happens near the top of the hour. The owls were at 5:55am and the grackle was at 8:55 am.

I know it sounds gruesome, one bird eating another but around here it is commonplace to see animals with other animals in their mouths so it doesn't bother me too much. Roadrunners with lizards dangling from their beaks or hawks carrying something furry. The most fantastic of those was years ago when I first moved out here(and it was much more rural) was a hawk carrying a live snake in the air. The snake was actually moving in the claws. I was driving in my car and actually stopped in mid road to watch for the few seconds he was in my sight. Can't do that today, too many cars now.
