Fascinating, Lisa. Thanks for sharing the link.
Pre-Covid, we used to visit a lake town south of here a few times a year. There is a boat tour that goes around the lake and into canals and goes past a huge eagles nest. Sometimes the pair are there. Beautiful site.
We have a large re-shouldered hawk in our neighborhood and for the first time this morning, I saw him with a mate. Plan on keeping an eye on those two!
