I saw some guy flying one over the heads of the Canada geese who hang out in the local reservoir. They were not impressed. First time I ever saw Canada geese bristle up their feathers and tilt their heads to look up at the weird thing in the sky through one eye. I am not a fan. I think they have their uses, but harassing wildlife is not one of them.
Incidentally, there was a YouTube video going around a while back of some guy at a Russian medieval festival taking a drone down by throwing a medieval spear at it. The headline read something like "8th century technology takes out 21st century technology at Russian Middle Ages festival."
