Common Terns form a large, off-season roost on Nooordhoek Beach, Cape Peninsula, every southern summer. Thousands of these dainty birds aggregate in the late afternoon just offshore of the beach. Some flocks of 10s to 100s of terns move directly on to the beach and its adjacent lagoon, while others feed for periods in the surf-zone. The latter form regimented trains, aligned against the wind, each dipping rhythmically into the foamy water to emerge with tiny fish or larval crustaceans. This relative close-up image catches the delicate post-splat moment of a single birds feeding and working its way to shore.
