, The mallard is widely distributed across the Northern and Southern Hemispheres; in North America its range extends from southern and central Alaska to Mexico, the Hawaiian Islands, across the Palearctic, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia and Britain to the north, and to Siberia, Japan, and South Korea,.  Hunting mallards might cause the population to decline in some places, at some times, and with some populations. Wipe the duck inside and out with a paper towel. The females give a large series of quacks while the male communicates by a soft rasping “rab”, and also grunts and whistles. The bill is yellow or orange with variable splotches of black and the legs are orangy-red. , Mallards are opportunistically targeted by brood parasites, occasionally having eggs laid in their nests by redheads, ruddy ducks, lesser scaup, gadwalls, northern shovellers, northern pintails, cinnamon teal, common goldeneyes, and other mallards. It is important to provide heat, especially for ducklings. The Mallard couple only until the female lays the eggs. Mallards are thought to be the most common duck on the planet. Be careful you are not “stealing” chicks from their mother before she returns.  The female gadwall (Mareca strepera) has an orange-lined bill, white belly, black and white speculum that is seen as a white square on the wings in flight, and is a smaller bird.  It does not need to be hung before preparation, and is often braised or roasted, sometimes flavoured with bitter orange or with port. Also in the east, it ranges to south-eastern and south-western Australia and New Zealand in the Southern hemisphere.  As it nears a month in age, the duckling's plumage starts becoming drab, looking more like the female, though more streaked, and its legs lose their dark grey colouring. 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). It is a common pastime for children to feed ducks bread, it is important, however, that they are fed on land and not in the water, the reason for this is that bread creates build up of excess toxins in the water which causes botulism (food poisoning) and untreated this is potentially fatal.  This change in plumage also applies to adult mallard males when they transition in and out of their non-breeding eclipse plumage at the beginning and the end of the summer moulting period. The repetition and frequency modulation of these quacks form the auditory basis for species identification in offspring, a process known as acoustic conspecific identification. Domestic ducks have no territorial behaviour and are less aggressive than mallards. , Since ancient times, the mallard has been eaten as food.  They were first domesticated in Southeast Asia at least 4,000 years ago, during the Neolithic Age, and were also farmed by the Romans in Europe, and the Malays in Asia. Grey ducks have a pale head with a conspicuous dark facial stripe and grey bill.  During the final period of maturity leading up to adulthood (6–10 months of age), the plumage of female juveniles remains the same while the plumage of male juveniles gradually changes to its characteristic colours. Trevor the duck was named after New Zealand’s parliamentary speaker, Trevor Mallard.  The majority of the mallard's diet seems to be made up of gastropods, insects (including beetles, flies, lepidopterans, dragonflies, and caddisflies), crustaceans, worms, many varieties of seeds and plant matter, and roots and tubers.  These eggs are generally accepted when they resemble the eggs of the host mallard, but the hen may attempt to eject them or even abandon the nest if parasitism occurs during egg laying. In the Hawkes Bay Game Region, Fish & Game New Zealand have a mallard/grey daily bag limit of 6, comprising no more than 2 hen mallards and 3 grey duck for the season 2 May to 14 June 2009. The scientific name for the Mallard Duck is Anas Platyrhynchos. The mallard (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurosiberia, and North Africa and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. , The mallard inhabits a wide range of habitats and climates, from Arctic tundra to subtropical regions.  He gave it two binomial names: Anas platyrhynchos and Anas boschas.  The hybrids of mallards and the yellow-billed duck are fertile, capable of producing hybrid offspring. , Due to the variability of the mallard's genetic code, which gives it its vast interbreeding capability, mutations in the genes that decide plumage colour are very common and have resulted in a wide variety of hybrids such as Brewer's duck (mallard × gadwall, Mareca strepera). Put 15g of butter, the parsley and the half orange inside the bird and truss. Mute swans (Cygnus olor) have been known to attack or even kill mallards if they feel that the ducks pose a threat to their offspring. The green head and yellow bill of the mallard duck is a familiar sight to many people living in the Northern hemisphere. Their numbers increase during wet periods and decline when there are droughts in the middle of the continentover the last 50 years their estimated numbers have cycled between about 5 million and 11 million.  In summary, the problems of mallards "hybridising away" relatives is more a consequence of local ducks declining than of mallards spreading; allopatric speciation and isolating behaviour have produced today's diversity of mallard-like ducks despite the fact that, in most, if not all, of these populations, hybridisation must have occurred to some extent. Hatching weekly year-round. The ducklings are precocial and fully capable of swimming as soon as they hatch.  Water depths of less than 0.9 metres (3.0 ft) are preferred, with birds avoiding areas more than a few metres deep. We use givealittle.co.nz to take donations via credit card and givealittle vouchers (a great gift idea). The Mallard Duck is also known as the Wild Duck Mallard Ducks are the most abundant and widespread of all waterfowl. , Mallards are also preyed upon by other waterside apex predators, such as the grey heron (Ardea cinerea), European herring gull (Larus argentatus), the wels catfish (Silurus glanis), and the northern pike (Esox lucius). The mallard was one of the many bird species originally described in the 1758 10th edition of Systema Naturae by Carl Linnaeus.  They measure about 58 mm (2.3 in) in length and 32 mm (1.3 in) in width. Givealittle also allows you to leave a message of support with your donation, allowing both us and others in the community to see your support for the birds of New Zealand.  The eggs are laid on alternate days, and incubation begins when the clutch is almost complete. Mallard hybrid, with "normal" Mallard inset for reference. Domestic ducks typically serve two to four. The mallard/grey limit in Taranaki is 10, and in Southland it is 15 from 4 May to 26 July. , In addition to human hunting, Mallards of all ages (but especially young ones) and in all locations must contend with a wide diversity of predators including raptors, mustelids, corvids, snakes, raccoons, opossums, skunks, turtles, large fish, felids, and canids, including domesticated ones.  Also, mallards may be attacked by larger anseriformes such as swans (Cygnus spp.) Also, the population size of the mallard is very large.  At this time she is left by the male who joins up with other males to await the moulting period, which begins in June (in the Northern Hemisphere). They do migrate for mating and to avoid cooler weather times of the year. , Several species of duck have brown-plumaged females that can be confused with the female mallard. © 2020 New Zealand Bird Rescue Charitable Trust, Entanglement – such as nylon, cotton or tape wrapped around their legs, plastic bottle rings caught around their neck or beak.  However, in 2017 a flock of mallards in Romania were observed hunting small migratory birds, including grey wagtail and black redstart, the first documented occasion they had been seen attacking and consuming large vertebrates.  In North America, adult mallards face no fewer than 15 species of birds of prey, from northern harriers (Circus hudsonius) and short-eared owls (Asio flammeus) (both smaller than a mallard) to huge bald, (Haliaeetus leucocephalus) white-tailed (H. albicilla) and golden eagles (Aquila chrysaetos), and about a dozen species of mammalian predator, not counting several more avian and mammalian predators who threaten eggs and nestlings. Mallard Ducks are included in the family Anatidae and subfamily Anatinae. The female Mallard (hen) is mottled dark brown, buff and white all over with the face being paler than the body, there is distinctive black line going through the eye.  Between three and four months of age, the juvenile can finally begin flying, as its wings are fully developed for flight (which can be confirmed by the sight of purple speculum feathers). Mallards are the most familiar and most widespread dabbling duck in the world, and knowing how to properly identify these ducks is the key to understanding the identification of all ducks, including picking out the mallard clues in hybrid ducks. Ducklings can swim and feed themselves insects as soon as they are born, they leave the nest soon after hatching, but stay near their mother for protection, warmth and education on how to cope in the wild. This blue patch is known as speculum, and it is most visible in flight.  Mallards are generally monogamous while domestic ducks are mostly polygamous. Mallard hens have a more mottled face and an orange bill with a black saddle.  A drake later named "Trevor" attracted media attention in 2018 when it turned up on the island of Niue, an atypical location for mallards.  Lebret (1961) calls this behaviour "Attempted Rape Flight", and Stanley Cramp and K.E.L. …  In certain countries, the mallard may be legally shot but is protected under national acts and policies. They are beautiful and the ancestor of most other duck breeds.  Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. Incubation takes 27 to 28 days and fledging takes 50 to 60 days.  Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds, as in case of the Greenland mallard which is larger than the mallards further south.
