I wasn't expecting to see more skimmers, but a beach near an old fort turned out to be one of their daytime resting places, and I was able to get quite close (with a nice long lens). On the ground they look like Spike Milligan's Milliganimal birds, all legs akimbo and looking rather unbalanced - quite the contrast to the grace of their flight.
Someone disturbed them, and the whole flock floated into the air for a moment, before descending to form in ranks, all facing out to sea.
Beautiful birds. I'm glad I've seen them.
