These elegant terns are flying in close formation as part of their courtship and pair-bonding rituals. They do this frequently, and often one bird (probably the male?) carries a fish, as seen in the lower right picture. These terns -- along with four other species -- were breeding at the Bolsa Chica wetlands in coastal Orange County, California.

For photo geeks, the pictures were all taken with a heavy but stabilized 500 mm lens, hand-held, at shutter speeds of 1/1600 or 1/2000 second. Modern photographic technology really works: with the excellent autofocus ability of the lens and camera, almost all the pictures I took were very sharply focused -- but most were in awkward poses, or with wingtips outside the frame, or in bad light (what you see here are the best of many). And the next day, I was very sore in the wrists and shoulders from hefting the heavy rig.
