Sadly raccoons got into the nest and apparently took the young right out of it as the nest is now empty and tipped sideways a few weeks ago. I know they weren't far enough along to fly out. And sure enough, within a few days the Great Blue Heron and Osprey were back. Next year if they nest again I will put an electric fence up to keep the raccoons out.
I know it's the way of nature but it still pisses me off.
At least the coons are staying out of the garden due to an electric fence.
