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. It has been introduced to New Zealand , Australia , Peru , Brazil , Uruguay , Argentina , Chile , Colombia , the Falkland Islands , and South Africa .
The breeding duck index in North Dakota, at 3.4 million birds, was up 1.5% from 2022 and 39% above the long-term average since 1948. "As with all May waterfowl surveys, we are counting what ...
The green-winged teal (Anas carolinensis) or American teal is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered conspecific with the Eurasian teal ( A. crecca ) for some time, but the two have since been split into separate species.
The breeding male is patterned grey, with a black rear end, light chestnut wings, and a brilliant white speculum, obvious in flight or at rest. [12] In non-breeding (eclipse) plumage, the drake looks more like the female, but retains the male wing pattern, and is usually greyer above and has less orange on the bill.
The mottled duck (Anas fulvigula) [note 1] or mottled mallard is a medium-sized species of dabbling duck. It is intermediate in appearance between the female mallard and the American black duck . It is closely related to those species , and is sometimes erroneously considered a subspecies of the former.
In 1924, their twelve-year-old son Charles A. Pilling (October 6, 1911 – October 24, 2001) dug a small pond to care for three injured mallard ducks he had been given. [2] This began Pilling's lifelong interest in breeding waterfowl. Over the years, the size of the pond was expanded to 100 by 50 feet (30 m × 15 m) on the half-acre lot.
Possible backcross between a Mallard and American black duck All the species within the mallard complex are known to hybridize with other members within overlapping ranges. Mallards, both domestic and wild in particular are notorious hybridizers, know to frequently hybridize within the mallard complex and even outside of Anas.
The hybrids often resemble a dark coloured mallard with a white breast. Mallard ducks also hybridise with the Muscovy duck producing pied offspring. Hybrids between the ruddy duck and white-headed duck are undesirable in parts of Europe [24] [25] where the introduced ruddy duck has bred with native white-headed ducks. The increasing number of ...
