Wild seals at RAF Donna Nook
Donna Nook is an RAF bombing range / nature reserve / Grey seal breeding site (I guess your coast has to multi-task on an island). This time of year (October - December) is the breeding season.
This pic shows the different stages of pup growth - although that final bow is optional (he was just posing for the cameras).
I've presented these in black an white cos it was a really overcast day and the colours are all washed out.
