‘Britain’s wildlife safari’: baby boom in Norfolk as seal colonies flourish

Grey seals are growing in numbers on England's east coast as a result of environmental safe havens and cleaner North Sea waters

It is a cold winter's day to be lying on a beach, but the seal pup suckling from its mother doesn't mind. A few metres away, a pregnant seal is burrowing into the sand, trying to get comfortable, while a third seal, which has just given birth, is touching noses with her newborn pup.

The shoreline - a mass of seals and their white pups - is one of Britain's greatest wildlife success stories: a grey seal colony on the east Norfolk coast.
