I watched the cameras some last spring/summer. We have a quite a few around me here in Southern Wisconsin. They love to catch fish on the Rock River and quite a crowd of viewers can be seen parked along the river watching them fish. I often see them fly overhead in route to the river. No matter how high up they fly, on a clear day you can still see that bright white head. I always have to stop what I'm doing and just stand and watch them.
