The Donna Nook nature reserve on the North East Coast of Lincolnshire lies on a flat expanse of salt marsh used throughout the year as an RAF bombing range, but between late October and December bombing stops and tens of thousands of visitors flock to the area to see the a large colony of Grey Seals who have been coming ashore to give birth since the late 70's. Only a low fence separates the visitors from the seals and more often than not pups will be lying tantalizingly close to the fence gazing up with big round eyes. The Lincolnshire Wildlife Trust reported over 1800 pups had been born by the end of November 2018 which even included a few rare jet Black Pups. Grey Seals are notoriously territorial and new mothers will warn off any other seal that ventures too close to its young pup.
