Whilst laying, the female needs a lot of nutrition so will leave the nest, sometimes for longer periods of time to feed and rest. Once all her eggs are laid she will rarely leave the nest; unlike osprey, the male does not bring food to the female whilst she incubates. This means that when she does require a short break to feed, toilet and stretch her legs the eggs are left alone. Whilst she is away, the nest is it at risk to predators such as crows, jays, mink, foxes and rats. The female will always cover her nest with vegetation such as leaves and grass to hide the eggs. One of the reasons which mallards lay so many eggs, is because there is a significant chance not all the young will reach maturity. This way there is hope that one or two of her chicks will survive. Mallards will also often lay more than one clutch in a season to increase the chances of their offspring reaching maturity.

The chicks hatch after 23-30 days, and despite being laid separately, they will all hatch around the same time. The chicks are mobile and ready to feed very soon after hatching, they will stay in the nest for just 10 hours to learn how to use their legs. Once ready to leave the nest the female will lead them to the nearby water body.

8-5-2019 OLIVA MARJAL, VALENCIA - MALLARD (FEMALE AND YOUNG) (Anas platyrhynchos)

Female mallards, or hens, have mottled brown and buff plumage for camouflage and build their ground nests near water. They are responsible for laying between nine and thirteen eggs, incubating them for about a month, and leading their ducklings to food and water after they hatch. Both sexes have an iridescent purple-blue speculum on their wings, bordered by white. 

Appearance

Plumage: Mottled brown and buff feathers provide camouflage, especially on the ground.

Head: A dark crown and an eye-stripe are visible, with buff cheeks and a darker throat.

Bill: The bill is orange with dark markings.

Wings: Both males and females have a distinct iridescent purple-blue "speculum" on their wings that is edged with white. 

Nesting and reproduction

Nest building: They build nests on the ground, often in a depression lined with grasses, leaves, and down from their own bodies.

Eggs: A typical clutch has nine to thirteen eggs, though they can lay up to 18.

Incubation: The female incubates the eggs for about a month.

Parental care: Once ducklings hatch, they are able to walk, swim, and feed themselves, but the female leads them to food and keeps them safe. 

Diet and behavior

Diet: As omnivores, they eat aquatic vegetation, insects, worms, and snails.

Adaptability: Mallards are highly adaptable and can even nest in urban areas like city parks if a small body of water is nearby.

Flight: They are known to be able to take flight directly from the water when alarmed.

19-7-2018 CAMI LES FONTS OLIVA, VALENCIA - MALLARD (FEMALE AND YOUNG) (Anas platyrhynchos)

The Mallard, or wild duck (Anas platyrhynchos), is a familiar and widespread dabbling duck with a presence across temperate and subtropical regions of the Americas, Eurasia, and North Africa. It has also been introduced to parts of the Southern Hemisphere. The male is renowned for its iridescent green head and white collar, while the female sports a brown-speckled plumage. Both sexes boast a speculum—a patch of feathers with iridescent purple or blue hues bordered by white. The Mallard's length ranges from 50 to 65 cm, with a wingspan of 81 to 98 cm, and it typically weighs between 0.7 and 1.6 kg.

Males during the breeding season are unmistakable with their glossy green heads, white collars, and purple-tinged brown breasts. Females are mottled brown with buff cheeks and an eye-stripe. Both sexes have the distinctive speculum on their wings. The male's bill is yellowish-orange tipped with black, while the female's is darker, ranging from black to mottled orange and brown.

Mallards are found in a variety of wetlands, including parks, small ponds, rivers, lakes, and estuaries. They prefer water depths less than 0.9 meters and are drawn to areas with aquatic vegetation.

This species is distributed across the Northern and Southern Hemispheres, from Alaska to Mexico, the Hawaiian Islands, across the Palearctic, and down to southeastern and southwestern Australia and New Zealand.

The mallard (/ˈmælɑːrd, ˈmælərd/) 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. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.

The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). Unlike many waterfowl, mallards 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 waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.

1-5-2016 VILLALONGA RESERVOIR - MALLARD (FEMALE AND YOUNG) (Anas platyrhynchos)

Male Mallards have a dark, iridescent-green head and bright yellow bill. The gray body is sandwiched between a brown breast and black rear. Females and juveniles are mottled brown with orange-and-brown bills. Both sexes have a white-bordered, blue “speculum” patch in the wing.

Unlike larger waterfowl such as the Tundra Swan, which mate for life, Mallard pairs only stay together for a season. Courtship and pair formation begin each fall and winter. Groups of males display for a hen with a variety of behaviors, including head and tail shaking, head-bobbing, dipping, and whistling.

The female Mallard has between five and 14 light green eggs that she incubates for 30 days.

The ducklings are lead to water as soon as their soft, downy feathers are dry. ...

Most Mallard ducks live for one or two years, but some can live as long as 16 years!

Mallards swim with their tail held above the water.
