Бурая кланяющаяся крачка Anous stolidus

Dark-bodied tern of tropical offshore waters, rarely seen from mainland. Breeds in colonies on rocky and sandy offshore islets. Sometimes found with offshore feeding flocks of boobies and other terns. Feeds by picking from the surface, not plunge-diving like most terns. Adult solidly dark brown with white cap. White limited to the forehead on immature.
