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.
The male birds (drakes) have a glossy green head and are grey on wings and belly, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black speculum feathers which commonly also include iridescent blue feathers especially among males. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.
