The Cormorant was swimming low in the water with his catch, probably a crab based on the parts you can see sticking out in a couple of the images.
Alas, a Laughing Gull spotted him and dropped in for a closer look.
The Cormarant dodged the gull and kept his prize.
The gull rose up a for another try.
Attracted by the activity a second gull joined in the harrassment.
The Cormarant dodged the interlopers and swallowed his lunch before the gulls re-grouped.
