The seal pups of Yorkshire

Seal pup numbers have increased from last year with over 800 pups born at the reserve so far.
Large bull seals are the first to arrive at the reserve in late October or early November where they will wait for females. The cows arrive later and are herded into harems by the bulls, where they give birth to a single pup which is covered in white fur. The seals return to the North Sea in January before returning to the same area to give birth the following year.
The Donna Nook reserve is the U.K.'s premier destination to see Gray seals and thousands of visitors from across the country come to see the wildlife spectacle every year.
