Cruel yobs are thought to have ripped the beak off a Canadian goose in a “vicious attack”.
Jason Margrave visited Wilton Park, in Batley, with his children on Monday, where he found the goose in distress.
They went over to feed the animal but saw the bottom part of its beak was missing, leaving it struggling to eat.
The father was told by a man in the park a group of teenagers had attacked the goose, and killed another goose just weeks earlier.
He was also told the yobs had harmed other geese in the park, treating it as a game to hurt the animals.
Mr Margrave immediately contacted the RSPCA.
He told the News: “These acts are cruel and we were really upset because this poor goose wasn’t able to feed due to only having part of its beak. We helped it by physically placing bread in its mouth but it couldn’t do it itself.
“It also had its tongue hanging to the side as there was no bottom beak to keep it in place.”
A video of the injured goose being fed was posted on Facebook, where people expressed their concerns for the animal.
News of the vicious attack has also gone global.
Carmen Hall, who lives in Florida but used to live in Batley, contacted the News saying: “This is absolutely horrific. How could anyone do this?
“I have spoken to the RSPCA myself but they said it was not classed as an emergency, but these cruel actions must be stopped.”
Readers were left appalled by the news and left comments on the Batley & Birstall News Facebook site.
Spokeswoman for the RSPCA Leanne Plumtree said an animal collection officer visited Wilton Park twice this week but had been unable to capture the animal.
She said: “The bird is missing its lower beak, resulting in it being unable to feed. This would likely be an un-treatable injury even if the bird wasn’t a non-native species.
“Under the Wildlife and Countryside Act, it is illegal for anyone, including the RSPCA, to return a non-native species to the wild once removed.
“We don’t know how this injury happened, and at the moment have no specific evidence that it was caused by a deliberate attack.”
