Bottoms Up!
Mallard ducks (Anas platyrhynchos) are known as "dabbling ducks", meaning that they don't dive when feeding, but rather tip over, tails up. They eat aquatic plants, seeds and other small stuff they can find, like snails. So, if you are trying to take a picture of one those beautiful iridescent green-headed ducks, and they do this in your direction...it's not you, they're just hungry ; -)
