The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN), and, unlike many waterfowl, are considered an invasive species in some regions. 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 ...
In the mid-20th century, mallards were introduced to Africa and as the invasive population size has grown, concerns over possible hybridization with the yellow-billed duck have occurred. This fear is fueled by other examples of invasive mallards causing localized extinction of other native ducks around the world because of hybridization. [8]
A male mallard duck. Subfamily: Aythyinae, diving ducks (Some 15 species of diving ducks, of worldwide distribution, in two to four genera; The 1986 morphological analysis [10] suggested the probably extinct pink-headed duck of India, previously treated separately in Rhodonessa, should be placed in Netta, but this has been questioned. [15]
The Mexican duck, a species with a relatively small population experiences gene flow from both the Mottled duck and Mallards. This dilution of pure genes due to the propensity of species within the mallard complex to hybridize and backcross could cause issues for the genetic purity of the species.
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

The Mariana mallard or Oustalet's duck (Anas oustaleti) is an extinct species of duck of the genus Anas that was endemic to the Mariana Islands.Its taxonomic status is debated, and it has variously been treated as a full species, a subspecies of the mallard or of the Pacific black duck, or sometimes as a subspecies of the Indian spot-billed duck.
Named by Lionel Walter Rothschild in 1892, the Laysan duck is named after Laysan island, one of the Northwestern Hawaiian Islands.It is a member of the mallard clade of dabbling ducks, and is a highly unusual species, both behaviorally and genetically.
