The magpies that show up here have gotten trained to hunt down and eat any starlings that I don't get a clean quick kill on. The ones that drop dead, they clean up for me.Instead of crows, I have magpies. There are three pairs of them, and they act very much like crows.
The crows and ravens are just fly byes for the most part. Sometimes in the fall they will make a short stopover to dine on the Russian Olives.
