How about a warning shot, in their deduction.
Not in this residential neighborhood. The only thing I shoot is my shrouded-barrel 22 pellet pistol. Yesterday morning I walked over to the neighbor's tree, and the neighbor's wife was working in the garden under the tree while the crows were raising hell. I asked her what she did to piss off the crows, and she said: "I thought it was your handiwork!". I bent down and picked up a dead Starling and said: "No--THIS is my handiwork."
All is quiet this morning. Guess whatever the crows were harrassing is gone. When I'm out coyote hunting, sometimes I put out my Squawking Magpie decoy, and play crow calls on my e-caller, and crows, magpies and hawks come in from miles away to see what the commotion is!
