The Royal Tern (Thalasseus maximus) is a seabird in the tern family Sternidae. It breeds on the Atlantic and Pacific coasts of the southern USA and Mexico into the Caribbean. American birds winter south to Peru and Argentina, and African breeders move both north and south from the breeding colonies. African birds may reach as far north as Spain. This species has also wandered to western Europe as a rare vagrant, these records probably being from the American colonies.
