I killed a bird

Not deliberately anyway. I got up in the morning, put coffee on, and then went outside to get the paper in the driveway, unaware of the events that were about to be put in motion. If I had gotten up a little later or earlier, perhaps then things would have been different. As I walked between the truck and car in the driveway and approached the paper out near the sidewalk, a cat which roams the neighborhood, came out from under the car. I ran at it to scare it off our property. The feline ran down the sidwalk in front of the neighbor's house. Garbage and recylcling had been out in the neighborhood and there were birds around the neighbor's recycling walking and pecking around the curb. The cat, running down the sidewalk, veered to the left at the birds, and the next thing I knew he was running down the sidewalk with a feathered body in his mouth. I could only stand there and watch, being too far away to run at him in hopes he would drop the bird. I say "I killed a bird" only because I assume the bird didn't survive.
