Discover the top 10 defining characteristics of ducks, including their unique physical features, behavior, habitat, and diet. Learn what makes these aquatic birds so special and well-adapted to their environment.

Duck is an aquatic bird that is located in the family Anatidae, this animal is found today in almost the entire world and the species that most characteristically represents it is Anas platyrhynchos domesticus, also known as domestic duck or Peking duck.

The domestic or farm duck has as its wild ancestor the Mallard, whose family also includes larger species such as the swan, the goose and the goose.

The domestic duck differs from the wild duck, among other things, in that it has almost completely lost its ability to fly by loss of strength in the wings, which are shorter and lighter. This is interpreted evolutionarily as a phenomenon of adaptation, since of having to feed themselves these birds happened to be fed by the human beings.

Characteristics Of Ducks

1. Neck and beak

Ducks are known for their unique neck and beak. Their necks are generally short and thick, with a curve that allows them to easily dip their head underwater to search for food. Ducks also have a distinctive beak that is flat and broad, with a serrated edge that helps them filter small aquatic creatures from the water. The color and shape of a duck’s beak can vary greatly depending on its species and gender. Overall, a duck’s neck and beak are well-suited for their aquatic lifestyle and play an important role in their feeding and survival.

2. Wings and legs

The ducks have rather short wings and webbed feet (animal palmípedo), that when folded they are very delayed with respect to the body, which grants them a quite elegant swim. However, his walking on land is quite clumsy. In domestic ducks the legs are much stronger than in the wild ones.

The body of the duck is rather round and is covered with feathers that can be white or other shades, including brown or black, sometimes with striking bluish and greenish. Males usually have more variety of colors than females. The ducklings are often yellow with an orange beak, there are also black pups. The colors of the beak are variable (orange, red, black).

3. Oviparous

Ducks are oviparous animals, which means that they lay eggs instead of giving birth to live young. Female ducks typically lay their eggs in a nest that they construct on land, often near a body of water. The eggs are incubated for several weeks until they hatch into ducklings. During the incubation period, the mother duck will often stay close to the nest to protect the eggs and keep them warm. Once the ducklings hatch, they are able to walk and swim almost immediately and are dependent on their mother for protection and food. The oviparous nature of ducks is a key adaptation that allows them to reproduce and thrive in their aquatic environment.

4. Life expectancy

How much do the ducks live? The duck lives on average about 9 to 12 years.

5. Weight

The weight of ducks can vary greatly depending on their species, age, and gender. In general, male ducks are larger and heavier than females. For example, a male mallard can weigh between 700 and 1500 grams (1.5 to 3.3 pounds), while a female mallard typically weighs between 500 and 1000 grams (1.1 to 2.2 pounds).


Other duck species can have different weight ranges, with some being much larger or smaller than mallards. For instance, the largest species of duck is the Muscovy duck, which can weigh up to 4.5 kg (10 pounds), while the smallest is the teal, which weighs only around 200-400 grams (0.4 to 0.9 pounds).

The weight of ducks can also be affected by their diet and living conditions. Domesticated ducks that are raised for meat production can be much larger and heavier than their wild counterparts.

6. Adaptation of the newborn duck

During the first 3 months of life, the ducks depend entirely on maternal protection, since the body is covered only by a sparse and heterogeneous plumage called down, which is not waterproof. In this stage they are very sensitive to extreme temperatures.

7. Adaptation of the Adult Duck

Adult ducks have several adaptations that help them thrive in their aquatic environment. Here are a few examples:

  1. Waterproof feathers: Ducks have feathers that are coated in oil, which helps to repel water and keep them dry. This allows them to swim and dive for extended periods without becoming waterlogged.
  2. Webbed feet: Ducks have webbed feet that help them swim and maneuver in the water. The webbing between their toes acts like a paddle, providing them with propulsion and stability.
  3. Flexible neck: Ducks have a flexible neck that allows them to reach and grab food from underwater without having to fully submerge their body.
  4. Serrated beak: The serrated edge of a duck’s beak helps them filter small aquatic creatures from the water, making it easier for them to find food.
  5. Good vision: Ducks have excellent vision both in and out of water, allowing them to spot predators and locate food from a distance.
  6. Specialized digestive system: Ducks have a specialized digestive system that allows them to extract nutrients from their food efficiently. Their gizzards, for example, have tough, muscular walls that help them grind up food before it enters their intestines.

Overall, these adaptations make ducks well-suited for their aquatic lifestyle, allowing them to find food, avoid predators, and survive in their environment.

8. Duck meat

Duck meat is very appreciated. The varieties of domestic ducks raised in the most widespread production farms in the world are the Beijing, appreciated as a variety of meat; La Bebería, from which it is obtained in addition to pate meat, and the Mulard, which arose from the crossing of the previous two and which is especially useful for obtaining “foie gras”. Other fairly widespread varieties are the Campbell and Bufe Arlington duck.

9. Temperament

With respect to its temperament, the domestic duck is a calm, peaceful animal, that coexists with the human without problems, also coexists well with other habitual pets (dogs, horses); On the contrary, the wild duck is much more unruly.

10. Feeding

Ducks are omnivorous and have a varied diet that includes both plants and animals. Their feeding behavior can vary depending on their species, habitat, and available food sources. Here are some common feeding habits of ducks:

  1. Dabbling: Many species of ducks, such as mallards, feed by dabbling, which involves upending their body in the water and using their bill to filter food from the surface or bottom of shallow water bodies.
  2. Grazing: Some ducks, like geese and swans, feed by grazing on grass and other plants in fields and meadows.
  3. Diving: Other species, such as mergansers and diving ducks, dive underwater to catch fish, crustaceans, and other aquatic creatures.
  4. Filter-feeding: Some ducks, such as the Northern Shoveler, have a specialized beak that they use to filter small invertebrates and plankton from the water.
  5. Supplemental feeding: In some areas, ducks are fed supplemental food by humans, which can include grains, seeds, and vegetables.

It’s important to note that feeding ducks bread or other processed foods can be harmful to their health and is not recommended. Instead, feeding them natural foods like seeds, grains, and vegetables, or providing them with a specialized duck feed can help keep them healthy and well-fed.
