The red-billed tropicbird is one of three closely related seabirds of tropical oceans. It looks somewhat like a tern, with mostly white plumage, some black markings on the wings and back, a black mask and a red bill. Most adults have tail streamers about twice their body length, longer in males. Three subspecies are recognised, and indicus, of the Middle East and Indian Ocean, is smaller with a more restricted mask and a more orange bill (Wikipedia, general species account).
It nests in loose colonies in a scrape on a cliff face that is easy to take off from. A single egg is laid and incubated by both sexes for about six weeks. Birds of all ages feed on fish and squid. The 2012 National Red List gives no status under this name.
