Bonnie et al;

I think it works the other way too. So, unless you saw the Red-tails working
from scratch, maybe the Great-horned is reclaiming it!  I know some hawks
and owls and probably other large species will flip back and forth on the
same old existing nests in different years. Of course, they need to spruce
up for current use so you will see stick carrying / building activity going
on.  That is how the record Eagle nests get to be 2 tons in weight - over
many years.
