GRIMSBY, ENGLAND - NOVEMBER 24: A Grey Seal pup lies in the grass at the Lincolnshire Wildlife Trust's Donna Nook nature reserve on November 24, 2014 in Grimsby, England. Seal pup numbers have increased on 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 Cow's 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 UK's premier destination to see Grey Seals and thousands of visitors from across the country come to see the wildlife spectacle every year.
