Thankfully they don't fly at night like owls. But once they find a place that has prey just waiting to be taken, they will come back. I have told this before, I used to have pigeons beautiful white fan-tails. I went out one morning to feed them in what is now my chicken house and saw all these white feathers--then all these dead pigeons--then I looked up and was staring this hugh hawk in the face. He was sitting on one of the roosts. He was nearer two feet tall than one foot, hugh talons, etc. I slowly backed out and slammed the door. He had torn off the screen on one side and gotten in. He killed 14 of my pigeons. A shotgun blew him to hell. I think this hawk is the same kind and they are a protected species. so, it is just a hypo-thetical killing that took place before and will again this weekend if we see him again--that is for all the federal agents out there.
Yes, it's like foxes... I love hawks and I love foxes. But once they find a source of captive food, they DO keep coming back. And, unfortunately, that means we need to do what is necessary to protect our livestock.
Before my kids were born, I raise Jersey Wooly Rabbits. (a dwarf wool rabbit) We went though a Horrible time with raccoons killing them right in their hutches, inside our barn. They would terrorize them until they ran out of the safe (solid floored) nest boxes, and onto the wire mesh floor. Then they'd grab them and literally pull them through piece by piece. We'd come out in the morning and nothing would be left inside the hutch but a skull. (because it was too big to fit through the wire) I used to like raccoons, and I quickly got to hate them.
That summer was the big rabies plague among raccoons up here, and fortunately, it knocked the population back down to a size where they aren't marauding the way they did then. Otherwise, we would have had to shoot (or trap) them too.
I do everything I can to protect wild life... We leave a large portion of our property wooded, exactly for that purpose. But when they attack our domestic animals, right under our noses, we have to do something to protect them!!!
