Sexing mallards using wing feathers

Sexing mallards

Detailed Description

The sex of captured waterfowl is determined using multiple characteristics such as plumage and bill coloration as well as anatomical structure. The plumage of these mallard wings indicate that the animal in the foreground is likely a female and the animal in the background is likely a male because the white stripe anterior to the speculum extends onto the greater tertial coverts.
