A POST-MORTEM on a male swan found dead on the River Tyne in Haddington has revealed it starved to death.

The body of the mute swan was recovered by countryside rangers last Wednesday but no obvious sign of injury was found on it.

Police sent the body for a post-mortem, which has revealed a hole in its stomach caused by a medical condition which had left it unable to feed properly.

Earlier reports that the swan had been the victim of an attack by one of the males from two established pairs which had been raising young cygnets on the river have been ruled out.

A council spokesperson confirmed: "The post-mortem has found the swan died of natural causes."
