Years ago, we had a dead crow in our yard. We think our dog did it, but we didn't see. My wife and I dealt with it, but had a lot of crow onlookers. They were pissed.

For the next year or so, every time either my wife or I would walk out the door, if crows were in the vicinity they would sound an alarm until they were happy we weren't going to attack them. They never seemed to do that for the dog, though.
