This species feeds on small fish and squid, diving into the ocean to catch its prey. The Cory's Shearwater breeds on islands in the Mediterranean and can travel long distances to forage for food. It is also known for its long-distance migrations, traveling from its breeding grounds to winter in warmer waters.
