Mallard Ducks in Flight Art Greeting Card - "Green Heads"

This fine art wildlife greeting card features three male and two female mallard ducks midflight and approaching landing over still marshy waters. A looming sun and wispy clouds paint the trees and water in purples and pinks. Did You Know? Male and female mallard ducks (anas platyrhynchos) are quite different from each other both in appearance and sound. Instead of the female’s quack, a male mallard makes a raspy one and two-note call along with non-vocal sounds produced by hitting his beak against his flight feathers.
