Three juvenile Turkey Vultures were soaring over the North Pool at Chautauqua near the Pelicans on the mudflats. They would swoop down to the surface of the water and then back up, circling around, and beating their wings to gain altitude. I think they were taking something off the surface of the water, but couldn't see anything. A dead pelican was near by but they didn't seem to notice it. They soared in this manner along the dike between Chautauqua and Clear Lake, at the Goofy Ridge Access point.
I thought at first that they were Black Vultures. I had never seen Turkey Vultures behave this way, and I guess I have never seen juveniles up close, so I thought I had Black Vultures, but alas, they were not. I'll keep looking at vultures, in case one or two wander up this far north!
