Mr. Swan has resumed his habit of traveling from body of water to body of water within his territory. Why does he not travel during the summer months, primarily dwelling at Niles Pond? Swans molt each summer and during the molting period, they cannot fly.
Mute Swans molt when their cygnets cannot fly. The female (pen) begins to molt almost immediately after the young hatch. The male, or cob, waits until the female’s flight feathers have grown back completely. The reason for this staggered molting period is because swans use their wings in battle and to defend their young. The swan family will never be left defenseless with at least one of the pair’s set of wings fully functional. The molting period lasts anywhere from four to seven weeks.
