An unmistakable bird of coastal waters, famous for its huge bill with expandable pouch. Groups of Brown Pelicans fly low over the waves in single file, flapping and gliding in unison. Their feeding is spectacular, as they plunge headlong into water in pursuit of fish. Current abundance of this species represents a success for conservationists, who succeeded in halting the use of DDT and other persistent pesticides here; as recently as the early 1970s, Brown Pelican was seriously endangered.
