Vicious swan attacks Amsterdam boaters

A grouchy swan has been terrorizing the Amsterdam canals by attacking people who pass by. The swan is apparently only trying to defend its nest, but is doing so by flapping its wings and acting aggressively to boats, kayakers and even just people walking along the canals on Wittenburgergracht and Oostenburgergracht. http://stream.zoomin.tv/video/9F1089AC-B31E-3424-75766F3A994E5509_500k.mp4
