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.
Male and female mallards generally become physically mature around the same age. Mallards generally grow to body lengths of 15 to 16 inches, with wingspans of around 3 feet. The plumage of male mallards is a combination of green, brown and black. The males' heads are vivid green. The females and youngsters of the species, on the other hand, are a dull brownish color all over their bodies.
