They're beautiful and elegant, but they can actually be incredibly dangerous -and in rare instances, deadly. Swans are highly territorial and will attack, aggressively flapping their strong, boney wings and snapping their beaks at people. In one unbelievable story, a canoe r was drowned after a swan knocked him from his boat and then stopped him from being able to swim to shore. The man's widow even sued the lake for housing such violent and dangerous birds.
