Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. Unlike many waterfowl, mallards are considered an invasive species in some regions. The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). The ducklings are precocial and fully capable of swimming as soon as they hatch. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. ![]() The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings males especially tend to have blue speculum feathers. Males have purple patches on their wings, while the females (hens or ducks) have mainly brown-speckled plumage. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. The mallard ( / ˈ m æ l ɑːr d, ˈ m æ l ər d/) or wild duck ( Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. Currently, there are more than 11 million of these ducks in the United States alone.Possibly extant and introduced (seasonality uncertain) The Mallard is highly adaptable, so its population hasn’t suffered as much as some other animals due to habitat loss and environmental change. Mallard Ducks Have a Strong Population Image Credit: Jahor, Shutterstock He wrote about the bird in 1758 and created a name for it that was a combination of a Latin word meaning “duck” and a Greek term for “broad-billed.”ġ3. The first known description of a Mallard duck is by Carl Linnaeus, whom many consider to be the father of taxonomy. We’ve Known About the Mallard for a Long Time Who knows how long this bird would have lived had it not encountered the hunter or how many other birds live this long?ġ2. In one case, a Mallard shot by a hunter in 2008 had a tag on its leg that a biologist had placed there in 1981, making the bird more than 27 years old. Most Mallard ducks tend to live 3 to 5 years, but some can live longer. A Mallard Can Live a Long Time Image Credit: NickyPe, Pixabay ![]() The other wild duck that has been domesticated is the Muscovy, but it’s not as popular as the Mallard.ġ1. Selectively breeding these domestic birds helps breeders create traits that they desire, like higher egg production or thicker plumage. The Mallard is one of only two wild ducks that humans have learned to domesticate, and most modern domestic varieties are descendants of it. The Mallard Is an Ancestor to Domestic Ducks Artificial habitats, like swimming pools or fountains, will work just as well.Ĥ. The water doesn’t even need to come from a pond or river. One of the reasons that the Mallard duck is so common in the United States and other countries is that it can adapt to living in almost any environment as long as there’s plenty of water. ![]() The Mallard Duck Is Highly Adaptable Image credit: AnnaER, Pixabay He also likes to make rattling sounds by rubbing his bill against his flight feathers.ģ. The male Mallard does not quack and produces a raspy sound instead. The female produces the traditional quacking sounds that you expect from a duck, with two to 10 quacks that start loud and long and get shorter and softer. The male and female Mallard sound different from each other. The Male & Female Mallard Sound Different
