It's an osprey nest.

I couldn't stand it. I had to call my neighbor who is a wildlife biologist and ask him the name of the bird that made that nest. I knew I would drive myself nuts trying to think of it. It's an osprey which is a smaller bird then our bald eagles that we have here also. The eagles are top in the pecking order and get the best nesting sites along our river so the osprey have to use the power lines. They eat the fish out of the river and small things like mice. Now I can relax. Don't you hate it when you can't think of something? I seem to be doing that more all of the time lately.......
