Swans are large water birds belonging to the family Anatidae, which also includes ducks and geese. They are known for their long necks, broad wings, and strong bodies adapted to life in wetlands, lakes, rivers, and coastal areas. Several species exist around the world, such as the mute swan, the whooper swan, and the black swan.
Their feathers provide insulation and help them stay warm in cold environments, while their webbed feet allow them to move efficiently through water. Many swans feed mainly on aquatic plants, although they may also eat small aquatic animals, insects, or other available food sources.
Swans usually form strong pair bonds, and many species remain with the same partner for several breeding seasons. During nesting periods, both parents often take part in protecting and raising their young, called cygnets. Young swans are covered with soft feathers and gradually develop the appearance of adults as they grow.
Although swans can fly long distances during seasonal migrations, some populations remain in the same region throughout the year. These birds play an important role in wetland ecosystems by influencing plant growth and participating in the natural balance of aquatic environments.
