Remarkable pictures captured a vicious battle between two grey herons in which one of the giant birds tried to drown its rival.

The majestic and normally serene birds are occasionally glimpsed standing stock still on the riverside waiting to catch fish.

But Mr Spence, who took the pictures on Wednesday, captured a much more violent side of their nature.

He said: ‘I really thought it was drowned at one point. However, it did regain its composure and accepted defeat and flew off eventually.’
