The mallard is considered the most common duck species in the world. It is widely distributed across North America, Europe, and Asia and adapts easily to wetlands, lakes, rivers, and urban parks. Many domestic duck breeds are also descendants of the mallard.
What do ducks usually eat?
Ducks are omnivorous birds. Their diet commonly includes aquatic plants, seeds, grasses, insects, snails, small fish, and crustaceans. Some species focus more on plant matter, while diving ducks consume more animal-based food depending on habitat and season.
Do all ducks migrate?
Not all ducks migrate long distances. Many wild duck species migrate seasonally to find food and suitable breeding areas, while others move only short distances. Domestic ducks and some wild species living in warm regions may remain in the same area year-round.
What is the difference between dabbling and diving ducks?
Dabbling ducks feed mainly at the water’s surface or by tipping forward in shallow water, while diving ducks fully submerge to find food underwater. Dabblers usually have lighter bodies, while diving ducks have heavier builds and legs set farther back.
How long do ducks usually live?
The lifespan of ducks varies by species and environment. In the wild, most ducks live between 5 and 10 years, though some sea ducks can live much longer. Domestic ducks often live 8–12 years with proper care, nutrition, and protection from predators.
