Yup, you're living on borrowed time. If you have Cooper's hawks you will eventually lose some to them. The Cooper's don't need a long swoop and dive flight plan. They can drop out of the sky like a rock, and their best hunting is in the woods, chasing birds through the trees. That table isn't going to stop them one bit! They don't need to be able to take off with the bird either, they will shred their prey right there where they hit it! One dog can't be everywhere, all the time, and the cat won't deter him either. I have 10 cats that live outside and are terrific hunters, but the Cooper's will swoop them and birds in the yard right in front of them! Your turn for predation is soon coming my friend, sad, but true. Take precautions now..
