Duck is the common name for various species in the waterfowl family Anatidae, including swans and geese.

In the Anatidae family, ducks are divided into several subfamilies; since ducks are not considered swans and geese, they do not constitute a monophyletic group but a taxon-like type.

Ducks are mainly aquatic birds, mostly smaller than swans and geese, and can be found in fresh and marine waters.

Morphology

Ducks have an elongated and broad overall body plan and a relatively long neck, but not as long as geese and swans.

By being more oval, the body shape of diving ducks differs somewhat from this. The bill is typically broad and includes serrated pectins, particularly well-defined in the filter-feeding species.

The bill is long and heavily dented in the case of some fishing species. The scaled legs, more so in aquatic animals, are sturdy and well-formed and usually set far back on the body.

The wings are powerful and are generally short and pointed. Fast, continuous strokes are needed for the flight of ducks, requiring strong wing muscles in turn. However, three species of steamer duck are nearly flightless.

Many duck species are temporarily flightless during molding; during this time, they search for protected habitats with good food supplies. Usually, this mold precedes migration. The drakes of northern species also have lavish plumage, which is molded in summer to give the “eclipse” plumage a more female-like look.

Southern resident species usually exhibit less sexual dimorphism. However, there are exceptions, like New Zealand’s paradise shelduck, which is both distinctly sexually dimorphic and in which the female’s coloration is lighter than that of the male.

Typically, the hues of juvenile birds match that of the female. Female ducks have evolved to have a corkscrew-shaped vagina to avoid rape.

Feeding

Ducks are omnivorous animals that feed on aquatic plants, small fish, insects, and grubs, which implies that ducks can easily adjust to various conditions.

The duck’s ability to consume such a diverse quantity of food in water and on dry land makes ducks one of the most common birds globally since they are present on every continent, with the obvious exception of Antarctica.

A duck’s mouth contains rows of tiny plates that support their teeth, which enable them to filter water out of their beaks without wasting food. The duck’s sophisticated water filtering method is close to how a blue whale in the ocean feeds.

Distribution and Habitat

There is a cosmopolitan distribution for ducks. A variety of species continue to live on sub-Antarctic islands, including South Georgia and the Auckland Islands.

Many ducks have established themselves on oceanic islands, including Hawaii, New Zealand, and Kerguelen. However, many of these species and populations are endangered or have become extinct.

Some duck species are migratory, especially those that reside in the temperate and Arctic Northern Hemisphere. Nevertheless, those in the tropics are not typically migratory.

Some ducks are nomadic, especially in Australia, where rainfall is patchy and intermittent, searching for temporary lakes and pools that appear after localized heavy rain.

Breeding

Ducks typically have one partner at a time, although the partnership usually lasts one year. The larger populations and more sedentary species tend to have pair bonds that last for years.

Most duck species reproduce once a year, choosing to do so in favorable conditions like the spring/summer or wet seasons. Ducks build a nest before breeding and, after hatching, lead their ducklings to water.

Mother ducks are caring and protective of their young. Still, they may abandon some of their ducklings if they are physically stuck in a place they cannot get out of (such as nesting in an enclosed courtyard) or are not prospering because of genetic defects or sickness caused by starvation, hypothermia, or disease.

Ducklings can also be orphaned due to inconsistent late hatching; some eggs hatch after the mother leaves the nest and leads her ducklings to the water.

Most domestic ducks abandon their eggs and ducklings, and their eggs can be hatched under a broody hen or by artificial means.

Communication

Not all ducks are quack, contrary to common opinion! It is commonly recognized that only the females of most duck species produce a quacking sound. All ducks have a broad spectrum of calls to interact with each other, including whistles and grunts.

Threats

Ducks are vulnerable species, so ducks around the world have several predators. Duck predators vary from smaller animals like foxes, wolves, and even big fish to larger animals like crocodiles and humans.

Relationship With Humans

Ducks are farmed for their meat and eggs all over the world. Ducks are often reared on mass (down) for their feathers, which are most widely used in bedding, such as duvets and pillows.

In Asia, especially in China, which has the biggest duck economy in the country, domestic duck populations are believed to be at their peak.

Different duck species are eaten worldwide, and duck meat is especially beneficial to humans because of its rich flavor. Hunters also frequently hunt ducks because they are often seen as an easy target. The quiet nature of the duck suggests that responding to surrounding noise sometimes takes a while.

Ducks are also intensively farmed and are subject to awful conditions, as with other commercial farm animals, including chickens. Buyers of duck meat and eggs should only acquire organic or free-range items and avoid purchasing duck-down (feathers) bedding.

Ducks have adjusted well to aquatic life, and their webbed feet and unique water filtering system in their mouths enable them to move smoothly on the water’s surface.

The duck’s webbed feet often make it a lot easier for the duck to walk on the slippery river banks.
