While we're at it, how many Barn Swallow, Cliff Swallow, Cave Swallow nests has anyone seen not on a man-made structure?

Hi Bud,
I'm unaware of any peer-review articles on the subject,  but here's one I recall from a popular publication.


"The great majority of coastal osprey nests today are on artificial sites," says ornithologist Alan F. Poole, author of Ospreys: A Natural and Unnatural History. "On the New England coast between New York and Boston, it's close to 100 percent."
 "Like it or not, we've created populations that are dependent on human structures. Ospreys have become the purple martins of the raptor world."

Over the last decade or two, Ospreys have been adopting more and more
artificial nesting sites (power poles, pilings, cell towers, light poles,
platforms) for breeding.

In fact, I am starting to wonder if there aren't more "artificial" nests
now in western Washington than natural ones.

Anyway, I find myself in need of a few photos of natural Osprey nests, i.e.
those placed in trees/snags.

And although I am supposed to be a raptor biologist, I am no longer aware
of many such sites.

Anyone out there willing to share the locations of some local "natural"
tree nests (Whatcom, Skagit, Snohomish, King, Pierce, Island counties) so I
can go and get some photos?

Plus, I am really kind of interested in this apparent shift in nesting

Are we seeing the gradual demise of natural Osprey nesting sites?

Anyone out there working on this?
