Mallard by John Barnes

Ducks

Mallard

Anas platyrhynchos

ORDER: Anseriformes
FAMILY: Anatidae

Basic Description

If someone at a park is feeding bread to ducks, chances are there are Mallards in the fray. Perhaps the most familiar of all ducks, Mallards occur throughout North America and Eurasia in ponds and parks as well as wilder wetlands and estuaries. The male’s gleaming green head, gray flanks, and black tail-curl arguably make it the most easily identified duck. Mallards have long been hunted for the table, and almost all domestic ducks come from this species.

Find This Bird

Look for Mallards at local city or suburban parks, where they’re likely to be accepting food handouts from humans. If you want to see them in a more natural setting, visit a nearby pond or lake—Mallards are likely to be the ducks you most frequently see.

Backyard Tips

If you have a pond or marshy area on your property Mallards might be attracted to your backyard. Occasionally, Mallards have been known to show up in people’s swimming pools.

Consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on our Attract Birds pages. You'll find plans for building a nest box of the appropriate size on our All About Birdhouses site.

Cool Facts
- 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 identify—they may lack the white neck ring, show white on the chest, be all dark, or show oddly shaped crests on the head.
- The widespread Mallard has given rise to a number of populations around the world that have changed enough that they could be considered separate species. The "Mexican Duck" of central Mexico and the extreme southwestern United States and the Hawaiian Duck both are closely related to the Mallard, and in both forms the male is dull like the female. The Mexican Duck currently is considered a subspecies of the Mallard, while the Hawaiian Duck is still given full species status.
- Mallard pairs are generally monogamous, but paired males pursue females other than their mates. So-called “extra-pair copulations” are common among birds and in many species are consensual, but male Mallards often force these copulations, with several males chasing a single female and then mating with her.
- Mallard pairs form long before the spring breeding season. Pairing takes place in the fall, but courtship can be seen all winter. Only the female incubates the eggs and takes care of the ducklings.
- Ducks are strong fliers; migrating flocks of Mallards have been estimated traveling at 55 miles per hour.
- The standard duck’s quack is the sound of a female Mallard. Males don’t quack; they make a quieter, rasping sound.
- Mallards, like other ducks, shed all their flight feathers at the end of the breeding season and are flightless for 3–4 weeks. They are secretive during this vulnerable time, and their body feathers molt into a concealing “eclipse” plumage that can make them hard to identify.
- Many species of waterfowl form hybrids, and Mallards are particularly known for this, hybridizing with American Black Duck, Mottled Duck, Gadwall, Northern Pintail, Cinnamon Teal, Green-winged Teal, and Canvasback, as well as Hawaiian Ducks, the Grey Duck of New Zealand, and the Pacific Black Duck of Australia.
- The oldest known Mallard was a male, and at least 27 years, 7 months old when he was shot in Arkansas in 2008. He had been banded in Louisiana in 1981.
