Common Moorhens eat aquatic vegetation, as well as snails, worms, berries and fruit. Normally I see them picking along at the edge of the reeds. When I came across several paddling around in a pond covered in duckweed, it was sort of cool looking, so I stopped to take a picture. I noticed that one of them was tilting his head and laying it almost flat on the water to eat the duckweed. Not for nuthin’ but that is a pretty smart bird. It has figured out that you get more by the sideways approach rather they the straight down approach. I only saw the one bird do it. Amazing the things ya see.
