Ruddy Turnstone, Arenaria interpres, La Jolla, California. Huge flock of Ruddy Turnstones going in and out with the waves like a swarm of insects. It was absolutely mesmerizing watching them rush rhythmically in and out with the waves. At one point a hawk flew over and they all burst up into wing and, even then, zigged and zagged evasively in unison. An amazing sight to see if you ever get the chance.
