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.
Cool Facts. 1  The Mallard is the ancestor of nearly all domestic duck breeds (everything except the Muscovy Duck). Domestic ducks can be common in city ponds and can be confusing to identifyâthey may lack the white neck ring, show white on the chest, be all dark, or show oddly shaped crests on the head.
