Always associated with water, this large tern can be seen on river beaches, over lakes and marshes, or along the ocean throughout the world. It feeds on fish and crustaceans captured by diving headfirst into the water. Breeding colonies are on beaches and grassy hummocks near the water, and the nest is on the sand with some moss or grass. Parents continue to feed the young after they leave the nest for up to 7 months.

The four-digit banding code is CATE.
