Backyard Birding Black-bellied Whistling Duck

I looked for these ducks at our local wetlands in southern Indiana at the beginning of May with no luck. This evening, when fishing at our lake, a pair of Black-bellied ducks flew in and landed on the power line. I ran home, got the camera, and started filming. It was a good evening!
