These majestic swans were popular ornamental and park birds already in the Middle Ages. Louis XIV introduced swans to the Seine, and Napoleon issued instructions for their protection. During the 20th century especially, Mute Swans spread rapidly from ponds in palace gardens and parks. The pairs often remain together for life. They are known for their loud throbbing of wings in flight, their threat pose with neck curved back and their mating display. If necessary, they defend their nest and young by striking hard with their wings."}
