I learned from local birders that the Great Horned Owl I saw nesting near the Detroit airport this spring was sitting in the same nest used by a Red-tailed hawk in 2009. I think it is well know that these owls are opportunists when it comes to nesting and often use RTH nests.

The Utica eagle's nest was taken over from a heron rookery, and the Black Hand Gorge eagle's nest was a former great horned owl's nest. I think that is just what big birds (and some smaller birds!) do. I remember a few years ago when I went with OOS to The Wilds, someone pointed out a nest that had been used alternately by great horned owl and red-tailed hawks. For three years running, a mourning dove nested in the exact same nest, on a beam in a machinery shed at my uncle's farm. Then, this year, after sitting on the nest for a couple of weeks, it was gone, and nearby a robin constructed an identical nest to the one that had been used by the mourning dove. This leads me to believe that mourning doves are opportunistic, too, and that the dove I had watched was using an old robin's nest. I'm curious. Has anyone else observed other species of birds using nests they did not build themselves?

My reason being, I have friends that live in Cass Lake, which was supposed to be one of the most highly nesting areas for Bald Eagles. When I went up there we checked out all the Nests my friends knew about that you could easly get to, they were all taken over by Osprey. That leads me to think that they'll possible do the same here and take over the Eagle nests, unless they're supplied with artifical nest posts in the water especially. Just my thoughts.

They were nesting on the flight lights which was dangerous to the jets and the Ospreys. These young hatched-out with jets taking off and landing beside them, so they are not bothered by trucks, cars and motor boats. Perhaps it will take a few generations to seek natural nest sites. Another question on the subject: Do they nest in natural sites on the east coast? I've seen pictures of Opreys nests on bouys etc. Have they adapted to man-made structures out of convenience?
