East Sussex WRAS received several calls from members of the public at Hampden Park's Decoy Pond, after the parent swans started attacking their remaining cygnet from last year.
This is a natural phenomena for them to attack and chase of their previous young and can take place any when from October through to February. In the wild they would naturally fly off and find a non-territorial flock or their own piece of water to set up residence. Unfortunately in some park ponds the young are reluctant to fly off due to the feeding and abundance of food. This can lead to the cygnets getting seriously beaten up, injured and put into life threatening situations like being chased across roads.
