Swans are large, graceful birds known for their long necks and elegant appearance. They are often found in lakes, rivers, and ponds, where they glide smoothly across the water. Swans are social creatures and can often be seen swimming in pairs or family groups. Their feathers are usually white, but some species, like the Black Swan, have dark plumage. These birds are also known for their strong bonds with their mates, often forming lifelong partnerships. Swans are herbivores, feeding on aquatic plants, and they can be quite protective of their nests and cygnets, which are their young. Their beauty and grace have made them symbols of love and fidelity in many cultures.
