Dave,
Not sure if I've trained them, ..or they've trained me. Probably a bit of both !!!!

And they are still calling in the Starlings. Yesterday morning I heard one of them caw-ing from the compost pile. I looked out and right above the Crow in a black walnut sapling was a Starling. By the time I got the gun both left.
A little while later I heard the Crow again. Surprised that any bird was around with the winds and rain squalls, I looked out and there was a Starling at the base of the feeder. It had it's back to me so I opened the door and aimed. It turned toward me and I squeezed of a Predator. Dang I thought I must have missed because It took flight straight away toward the back of the property. I watched as it stayed low, flew into the edge of the brush line and fluttered straight down through the branches - never moving again.
I looked out the other side of the house and there were two more Starlings pecking for bugs in the lawn. The Trail XL going off hadn't spooked them. I had time to sneek out to my shed blind and slowly open the window. The Pred hit center mass and kicked up dirt and grass beyond the Starling as it fell over without a twitch.
Went out and retrived both.
The one that was breast shot had a very large exit wound in it's lower back. The Pred did major damage on the way out, but still this tough little guy was able to fly about 30 yards before dropping dead.
The second Starling, like other side shots, had wing feathers stuck into the chest entrance wound. The Pred easily passed through both wings and chest.
Put both birds on the lawn by the compost and within hours I heard a Crow caw-ing again and both were gone when I looked out. With the Crow's help I've manged to thin out the local Starling flook and recycle them.
Harmony !
