Mallard ducks average around 20 to 26 in length and can weigh 2 to 3 lbs. The male is known as a drake and the female is called a hen; the flocks are called sords when they are in flight. They are common in North American, Europe and Asia. The ubiquitous mallard is capable of cross-breeding with many other species.
Several species of duck have brown-plumaged females which can be confused with the female mallard. The female gadwall (A. strepera) has an orange-lined bill, white belly, black and white speculum which is seen as a white square on the wings in flight, and is a smaller bird.
