Are Swans Sea Birds?
Swans are a type of waterfowl, but they are not considered sea birds. While swans can be found in both freshwater and saltwater habitats, they typically prefer to inhabit lakes, ponds, rivers, and wetlands. They are also known to migrate long distances between their breeding grounds and wintering areas.
Habitat
Swans are most commonly found in temperate climates, although some species may inhabit tropical regions. They tend to prefer shallow bodies of water with plenty of vegetation for food and protection from predators. Swans will also use estuaries and coastal waters during migration or when searching for food.
Diet
Swans primarily feed on aquatic plants such as algae, pondweed, and duckweed. They will also eat small fish, crustaceans, mollusks, insects, and other invertebrates. Some species may supplement their diet with grains or other plant material.
