Lincolnshire’s Donna Nook Nature Reserve is one of the best, and most accessible, places in England to see grey seal pups up close – and December is the busiest month, with more than 1,600 born so far. Grey seals return every winter to give birth to their pups near the sand dunes and the reserve has a designated viewing area close to the dunes, while an online weekly ‘pupdate’ keeps a running total on the numbers. https://bit.ly/3R5FCvi
