Sometimes we would be tracked for miles by groups of sea gulls. They flanked the ship and seem to be watching the ship's wake. Every now and then would dive headfirst into the ocean, pop back up to the surface about 20 seconds later and take back to the air shortly thereafter.
Most of the shots taken were at the extreme range (840mm FFE) of my Canon SX40 but they seemed to come out OK.
Does anybody know the correct name, other than simply Sea Gulls, for these birds?
