I've never seen Ospreys nesting in trees in Ohio, but that might not
mean they're incapable of nesting in trees.  One possibility is that
Ospreys prefer manmade structures because of perceived superior
structural characteristics and/or high availability.  I'm not aware of
any actual data on this; it would interesting to remove all the
man-made structures in an area and see what the Ospreys do.

> One thought on Osprey nests in cell towers and other man-made structures:  Many of the Ospreys released in Ohio came from Langley Air Force Base - VA - near Washington DC.  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?
