So there I was sitting on the beach watching the gulls doing their gull stuff on the shore when I noticed that one of the group was doing his own thang. He was doing that foot vibration motion in the sand that you used to do as a kid on the mudflats to make you sink deeper (and oh yes, we used to get in trouble). It looked so amusing; the other gulls milling about, preening or napping and here is this one, head bent over in earnest, jiggling his feet.
He must have been finding some pretty tasty stuff, because he was repeatedly dipping his head to eat until a bigger gull came over and scared him off. Funny, the larger gull didn't do the foot jiggle, just stood around in a bossy, big-gull way. Hmph.
