The Family Anatidae includes ducks, geese, and swans, which are waterfowl widely distributed across freshwater and coastal habitats worldwide. Members of this family are adapted for swimming, with webbed feet, streamlined bodies, and waterproof feathers. They are generally herbivorous or omnivorous, feeding on aquatic plants, insects, and small fish. Anatids exhibit diverse behaviors, including migratory patterns, complex mating displays, and parental care, with many species forming long-term pair bonds. Ecologically, they play important roles in seed dispersal, nutrient cycling, and as a food source for predators, while also holding cultural and economic significance for humans.
