Nesting sites are typically on the ground, hidden in vegetation where the female's speckled plumage serves as effective camouflage, [90] but female mallards have also been known to nest in hollows in trees, boathouses, roof gardens and on balconies, sometimes resulting in hatched offspring having difficulty following their parent to water. [91]
The American black duck (Anas rubripes) is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas, weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with an 88–95 cm (35–37 in) wingspan. It somewhat resembles ...
The Mallard complex refers to closely linked members of the Anas genus found around the world thought to all be descended from one common ancestor. Species in the mallard complex are known for frequent hybridization amongst other members of the complex. The species within the complex can be very difficult to distinguish genetically, likely due ...
A drake mallard is photographed in a Wisconsin pond in March, 2022. North America's most abundant duck species, the mallard, was estimated at 6.6 million, up 8% from 2023 but 16% below the long ...
The northern pintail is a bird of open wetlands which nests on the ground, often some distance from water. It feeds by dabbling for plant food and adds small invertebrates to its diet during the nesting season. It is highly gregarious when not breeding, forming large mixed flocks with other species of duck.
The nest is usually placed in a hole in a tree, but sometimes an old nest of a corvid is used and occasionally the nest will be placed on the ground. The clutch of 8–10 pale cream eggs is incubated only by the female. The eggs hatch after 26–32 days. The precocial downy ducklings leave the nest site when dry and are cared for by the female ...
Gertie the Duck is a 4-foot-tall (1.2 m) bronze sculpture of the mallard duck created by sculptor Gwendolyn Gillen.

It stands on the northwest side of the Wisconsin Avenue bridge over the Milwaukee ...
