I was very lucky to be able to watch the birth of a Grey Seal pup at Donna Nook, Lincolnshire, on 13 November 2010.
The birth happened close to the fence in the viewing area of the dunes - too close for me to get the whole of the mother seal in frame, so I concentrated on the business end! The light was fading as the sun started to dip below the dunes and I was a bit concerned at first that she wouldn't manage to give birth before the light went. She timed it beautifully!
It was wonderful to watch and I'm sure I'll treasure the (many) photos I took.
