A cygnet had to be rescued by the RSPCA after a two-inch metal rod got stuck in its throat.
Members of the public called the charity after seeing the animal struggling to swallow at Oundle Wharf in Station Road, Oundle.
RSPCA inspector Polly Underwood went to check on the cygnet on Sunday. She said: “When I caught him, I could immediately feel that there was something stuck in his throat. It was a two-inch, very thin rod of metal which had pierced the skin on his neck.
“I took him to the vets, where it was discovered that he had an infection in his throat because the piece of metal had stopped food from going down into his stomach.
“The vet put him on a course of antibiotics and the piece of metal was removed. The cygnet is now being cared for at a private wildlife centre. We are hopeful that he will make a full recovery and will be returned to the wild very soon.”
The charity has warned people not to leave litter.
