Mallard

The mallard is the most familiar and recognizable duck in the entire world. Found almost anywhere in the Northern Hemisphere with a sufficiently large body of water, it is a type of dabbling duck that feeds near the surface of the water. The mallard has a long and complex history in human culture as a source of food, the target of hunters, and even occasionally as a pet.

4 Incredible Mallard Facts

• The familiar quack of the duck is actually the female’s call to her ducklings, which spend the early part of their lives following closely behind the mother.
• Almost all domesticated ducks have descended from the mallard. Domestic ducks were kept by the ancient Romans, Egyptians, and Chinese.
• Cooked duck is considered to be a delicacy in many places, including foie gras in France and Peking duck in China.
• One of the more unusual facts is that the mallard seems to hybridize very easily with closely related species. This is actually a problem for rarer duck species, like the Hawaiian duck, which might be overwhelmed or replaced by the hybrids.

Where to Find the Mallard

Mallards are found all across the Northern Hemisphere. Its natural range includes North America, Europe, Asia, and parts of northern Africa. They’ve also been introduced into Australia, New Zealand, and South America. Their preferred habitats are lakes, ponds, streams, and wetlands.

Nests

Mallards conceal their nests within heavy vegetation close to the water where they live and feed.

Classification and Scientific Name

The scientific name of the mallard is Anas platyrhynchos. Anas, which means duck in Latin, is a genus of 31 or so dabbling ducks found all over the world. Platyrhynchos is a combination of two different ancient Greek words: platus, meaning wide or flat, and rhunkhos, meaning beak.

Size, Appearance, and Behavior

The mallard is a medium-sized bird, measuring 20 to 26 inches, with a long neck, a rounded head, webbed feet, and a rather stout body. This species has a strong degree of sexual dimorphism, meaning that the sexes look quite different from each other in size and color. The male has the distinctive green or blue-headed plumage, the white ring on the neck, the brown wings and breast, the grayish body, and more green colors on the back of the wings. The female, by contrast, has light brown plumage with dark brown markings or stripes on the body, wings, and top of the head. Both sexes have yellow or orange bills and feet.

The mallard is a highly social species; outside of the breeding season, they form large flocks of varying sizes to forage and roost together. Mallards make use of numerous vocalizations and body language to communicate with each other. For instance, when dealing with a threat, the mallard will first display an open bill and then push up against the intruder with its chest. The females do most of the quacking, whereas the males are usually silent except during fights.

Migration Pattern and Timing

Northern populations of mallards travel hundreds or thousands of miles south for the winter. Popular destinations include the southern United States, northern Mexico, central and southern Europe, northern Africa, and central to southern Asia.

Mallard Diet

The mallard is an omnivorous bird. It feeds by a method called dabbling, in which it tips forward in the water and eats anything just below the surface.

What does the mallard eat?

The mallard’s diet consists of insects, worms, snails, and slugs, and all sorts of vegetation. Basically, it will opportunistically eat almost anything it can.

Predators, Threats, and Conservation Status

The mallard is currently considered to be a species of least concern by the IUCN Red List. While they are hunted in the millions every year for sport, they seem to reproduce rapidly enough to maintain numbers. Another significant threat to them is the loss of their natural wetland habitats, but fortunately, they appear to have adapted well to human-made ponds and lakes.

What eats the mallard?

The mallard is preyed upon by red foxes, coyotes, wild cats, and numerous birds of prey. The eggs and young chicks are also vulnerable to raccoons, opossums, skunks, turtles, weasels, large fish, and many other animals.

Reproduction, Young, and Molting

Depending on their range, the mallard’s breeding season starts as early as October and lasts until March. The male initiates courtship by shaking his head from side to side or rising in the water while flapping his wings. The female encourages this behavior by shaking her own head back and forth or paddling through the water with her head held low.

The pair usually begins nesting upon their return from their annual migration in the following spring. During mating, the blue-headed male will grip the female’s neck with his beak for stability. One of the more unusual facts about the male mallard is his corkscrew-shaped penis. It’s been hypothesized that the duck’s genitals evolved as the result of a lengthy sexual conflict. Since the duck’s reproductive season is so competitive, males evolved methods to deposit sperm much farther than their reproductive rivals. This is highly unusual when you consider the fact that many birds don’t even have visible penises.

After copulating, the female produces a clutch of 5 to 15 eggs. She incubates them for up to a month before they hatch. The young ducklings follow behind the mother and do not return to the nest. They have yellow and dark brown colors that begin to change after a month or two.

It takes about three or four months for the duckling to learn the art of flying. This is just in time for them to begin the arduous migratory journey. Once they’ve mastered the route, they will tend to return to the same spot year after year. The typical lifespan of the mallard is five to 10 years. Many end up falling prey to predators or human hunters. However, the oldest known mallard lived to be around 27 years old.

Mallard Population

Currently, there are between 9,300,000 and 17,260,000 mature mallards worldwide, and it is almost certainly one of the most common birds in the world. Unfortunately, numbers currently appear to be declining.
