This possibly is a female Hooded Merganser. I didn’t see her in the water and don’t see them often enough to really know. The Merlin app suggested an Anhinga, which it clearly is not. That was the first time I’ve had that app be way off base.

There was a small flock of Mergansers milling around in a an adjacent pond, in water that took on an odd color reflection.

Beutiful flight picture against the background.
Thanks, Hans!
I love that first picture 🙂
Thank you, Rudi! The background of reeds really made the image.
