Bridled terns are sea birds that can be found across the world, across many waters, islands and coastal areas, particularly around tropical oceans. The birds are also known to be migratory.They are carnivores, consuming a variety of fish, crustaceans, cephalopods and insects.
They are globally listed as being of least concern. However,although the broader species is thought to be secure, some populations may be more threatened than others. Some of their threats are human disturbance (particularly the disturbance of nesting sites and breeding colonies), predation and natural disasters.
