Cormorant on a rock in the river Seaton at Seaton in Cornwall, a small village on the county's far south east coast. This is near the river mouth just behind the beach. Think this animal regularly does this as have seen it in exactly the same place doing the same thing last time we visited.

You probably know this anyway but "after fishing, cormorants go ashore, and are frequently seen holding their wings out in the sun; it is assumed that this is to dry them. Unusually for a water bird, their feathers are not waterproofed. This may help them dive quickly, since their feathers do not retain air bubbles."
