[19] The Mariana mallard was a resident allopatric population – in most respects a good species – apparently initially derived from mallard-Pacific black duck hybrids;[118] unfortunately, it became extinct in the late twentieth century. Ducks spend much of their time in the southern portions of the United States and along the coastal fringes where weather conditions are mild. Its bill soon loses its dark grey colouring, and its sex can finally be distinguished visually by three factors: 1) the bill is yellow in males, but black and orange in females;[30][self-published source] 2) the breast feathers are reddish-brown in males, but brown in females;[30] and 3) in males, the centre tail feather (drake feather) is curled, but in females, the centre tail feather is straight. Also in the east, it ranges to south-eastern and south-western Australia[49] and New Zealand[50] in the Southern hemisphere.

The wild mallard was eaten in Neolithic Greece. [27] While most are not domesticated, mallards are so successful at coexisting in human regions that the main conservation risk they pose comes from the loss of genetic diversity among a region's traditional ducks once humans and mallards colonise an area. • Current address: Department of Natural Resources, Box 367, Grantsburg, Wisconsin 54840 USA.

The male birds (drakes) have a glossy green head and are grey on their wings and belly, while the females (hens or ducks) have mainly brown-speckled plumage. [41] Examples of this rule in birds are rare as they lack external ears, but the bill of ducks is supplied with a few blood vessels to prevent heat loss,[42] and, as in the Greenland mallard, the bill is smaller than that of birds farther south, illustrating the rule. [32], Several species of duck have brown-plumaged females that can be confused with the female mallard. It is 50–65 cm (20–26 in) long – of which the body makes up around two-thirds – has a wingspan of 81–98 cm (32–39 in),: 505 and weighs 0.72–1.58 kg (1.6–3.5 lb).

The exact amount of time needed to properly age will vary – on average; it will take between 3 – 7 days (after the meat has defrosted) for ducks, 8 – 14 days for geese. In the space of one year a duck experiences the full spectrum of seasonal changes that usher in opportunities and challenges. Found wild throughout the Northern Hemisphere, mallards have also been introduced to many other areas and can easily be found in ponds, lakes, and rivers, as well as in artificial habitats such as golf courses, parks, gardens, and even yards. Coastlines, mountain ridges and waterways such as the Mississippi River are major topographic features that may be considered landmarks. Breeding. This is because it has a large range–more than 20,000,000 km2 (7,700,000 mi2)[97]–and because its population is increasing, rather than declining by 30% over ten years or three generations and thus is not warranted a vulnerable rating.
