Although this region is the most typical destination of mallard migration routes, these ducks are occasionally spotted spending their winters elsewhere, sometimes as far south as the northern portion of Mexico. Some even prefer to winter in more northern spots, including the southern region of British Columbia. Mallards typically head south for migration anywhere between the end of August into December each year. Migration traffic is particularly heavy in both October and November, however.
They tend to return to their reproductive grounds in February and March. Not all mallards actually migrate, either, particularly if humans in a certain geographic location provide them with regular sustenance.

Majority of diet is plant material, including seeds, stems, and roots of a vast variety of different plants, especially sedges, grasses, pondweeds, smartweeds, many others; also acorns and other tree seeds, various kinds of waste grain. Also eat insects, crustaceans, mollusks, tadpoles, frogs, earthworms, small fish. Young ducklings may eat mostly aquatic insects. Pairs form in fall and winter.
Displays of male include dipping bill in water and then rearing up, giving whistle and grunt calls as he settles back on water; raising head and tail while giving sharp call; plunging forepart of body deep in water and then flinging up water with bill. Nest: Female, accompanied by male, seeks and chooses site for nest.
Site may be more than 1 mile from water; usually on ground among concealing vegetation, but may be on stump, in tree hollow, in basket above water, various other possibilities. Nest is shallow bowl of plant material gathered at the site, lined with down. Learn more about these drawings.
Fall migration extends over long period; migrates relatively early in spring. Since pairs form in fall and winter, male probably follows female to breeding areas. Feral populations may be permanent residents, but all wild Mallards in North America are probably migratory.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
Proposed rule cuts the public out of oil and gas leasing decisions for National Forests. Coastlines, mountain ridges and waterways such as the Mississippi River are major topographic features that may be considered landmarks. One nonvisual cue that aids in navigation is the Earth's magnetic field. When the Earth's magnetic field is obstructed migrating birds often change or alternate direction and altitude.
Homing, another nonvisual cue, is a bird's ability to find its way home when released in an unfamiliar place or direction. The ability to navigate over many miles from breeding to wintering grounds is an amazing adaptation. It is likely that most birds use a combination of visual and nonvisual cues, as well as homing. Navigation and migration behavior is very difficult to study therefore has not been full resolved.
Everyone knows that ducks fly south in the winter, but what do they do and where do they do it? Ducks spend much of their time in the southern portions of the United States and along the coastal fringes where weather conditions are mild. They leave northern nesting areas and head for a warmer climate for several reasons, least of which is because the weather is cold. During much of the winter ducks loaf about eating and storing up nutrients in preparation for the long trip back to the breeding grounds.
Waterfowl can withstand very cold temperatures, but when their food source is eliminated they must leave northern areas in search of mild temperatures. When shallow ponds or lakes freeze over with ice ducks can no longer reach aquatic plants and insects for meals. Ducks that feed on seeds or waste grain must also leave the area when snow falls cover their foods.
Ducks winter in mild areas where food is plentiful and the water rarely freezes like the Mississippi Alluvial Valley in the southern area of the United States. Another great wintering place for ducks is coastal northern California and along the central valley of California.
