The lesser crested tern (Thalasseus bengalensis, syn. Sterna bengalensis - see Bridge et al., 2005) is a seabird of the tern family, Sternidae. It breeds in subtropical coastal parts of the world mainly from the Red Sea across the Indian Ocean to the western Pacific, and Australia, with a significant population on the southern coast of the Mediterranean on two islands off the Libyan coast. Accidental breeding has also been reported in Italy and France. The Australian birds are probably sedentary, but other populations are migratory, wintering south to South Africa.
