I solved my problems by taking down the feeders. The birds really don't need our feed. Its just we like to watch them. Also you don't want to get bears interested in your yard and house. Or a nasty surprise can happen. Like them coming on the front porch and looking in the kitchen window. (gas barbecue grill on the porch and the recycle barrel).
Wild animals can be a real PITA but then, I moved into their back yard. Not the other way around. That hot wire should work good. It will be interesting to see how they act around it. I had a friend that put electric fences around his garden one year to keep the animals out.
