Feeding: Hovers and then plunges head-first into water to catch small fish.

Behavior at Wakodahatchee: The Least Tern is very common at Wakodahatchee in the winter, and flocks are observed daily on the roofs of the gazebos. They soar above all the open ponds to dive and fish. The Least Tern is migratory and disappears in the winter months to be replaced by the Forsters Tern. The least tern nests in the sand, and its nesting sites are easily disturbed by high tides or human intrusion. For this reason The Least Tern has become endangered in California.
