Common Tern - Sterna hirundo

Common Terns | Cemlyn Bay
Canon 800mm f6.3 for 1/2500th @ iso400

The tide was ebbing and a few rocks covered in seaweed were being exposed as the sea dropped back, the terns coming off the colony to feed, bathe and congregate took advantage of the newly exposed "perches". There was no way the three Common Terns who got onto this rock first where going to allow any other bird to land and join them and successive new arrivals where moved on.
