Red-billed tropicbird

Red-billed tropicbird.
The red-billed tropicbird is a seabird, one of three species in the family Phaethontidae. Resembling a tern, it has mostly white plumage with some black markings on the wings and back, a black mask and a red bill. Most adults have tail streamers that are about two times their body length, and generally longer in males than in females. Described by Carl Linnaeus in his 10th edition of Systema Naturae (1758), this species ranges across the Indian Ocean, the tropical Atlantic, and the eastern Pacific. Nesting takes place in loose colonies. A single egg is laid, and incubated by both sexes for about six weeks. After a chick fledges, the parents will usually stop visiting the nest and the chick will leave. Red-billed tropicbirds of all ages feed on fish and squid, catching them by diving from the air into the water. The birds sometimes follow surface-feeding predators that drive prey to the surface, where they can be seized.
