Hi Mark,
Thanks for the speedy reply about our Osprey migratory behavior and tree /
perch fidelity questions. I have seen your involvement with the Raptor
Research Foundation when you were with them and respect you contributions
and skills. I hope Alan Poole has some insight about the tree questions.
He has
been all over the Osprey literature and I have read some of his well-cited
works.

It sounds like a migratory stopover as you suggest. Radio-tracked birds do
show that behavior and I have seen similar things here in Minnesota,
although I have not noticed the same tree/perch used. I would guess by the
timing that those birds are probably heading north and taking on a bit more
food. I think both males and females do this.
I am copying Alan Poole and Rob Bierregaard on this, both of whom watch and
think about osprey a lot. They may have some thoughts.
Good luck with the nest hunt.

Hi Mark,
While searching for possible Osprey nests along a river in Northeast
Tennessee during the past two years, I have had two trees where an Osprey
arrives about the first or
second week of April and stays about a month, apparently without nesting.
They have returned to the same trees and the same perches in each tree both
in 2009 and now in 2010. I have not seen either bird with another Osprey.
Meanwhile, I have had the usual migration of Ospreys thru the region since
about March 26. Is this some type of
layover or stopping off point where they fuel their fat levels for a few
weeks before going on north ? Is this a behavior seen by just males or
females or both ? What do you think I am seeing here ? Thanks for you
expertise with this species.
