The RSPCA is appealing for information after a male swan is believed to have been attacked by dogs at Cusworth Hall and Park in Doncaster and had to be put to sleep.
The RSPCA caught the bird on Wednesday 23 July after a call from a concerned member of the public.
RSPCA inspector Sandra Dransfield said: “There was nothing we could do to save him, his injuries were just too severe.
“He had a large wound on his back, another on his chest and his neck had been torn open.
“We’ve been told he was attacked by several dogs the previous night, and that the dogs were deliberately set on him by a number of youths.
“We want to hear from anyone who saw anything or has any specific information about what happened on 0300 1234 999. They should ask to leave a message for me.”
It is illegal to kill, injure or take a wild bird under the Wildlife and Countryside Act 1981. The maximum sentence for anyone found guilty is six months in prison and/or £5,000 fine.
RSPCA inspector Dransfield said: “He leaves behind a female swan and two cygnets, which is extremely sad.
“We’re told the female had further cygnets which are missing, which is a cause for concern too given what we have been told happened to the male.
“We’re not legally able to remove the female and her cygnets as they are fit and healthy but this is a busy place, with lots of people regularly using the park for walking dogs and exercise. We hope people will help in keeping an eye on them, to make sure they’re okay.”
