Tropicbirds are amazing seabirds that live in warm ocean waters.

They belong to a special group called Phaethontidae. These birds are mostly white with very long tail feathers. Their bodies can be between 76 and 102 cm long. Their wingspans are also quite large, reaching up to 112 cm. They have large, strong bills and short, thick necks.

Because they live in the open ocean, they are called pelagic birds.

These birds have a very specific way of moving and eating. Their feet are totipalmate, which means all four toes are connected by webbing. Their legs are located far back on their bodies. This makes walking impossible, so they must push themselves forward on land. To eat, they hover over the water and then dive down. They usually only dive into the top layer of the sea.

They mostly eat fish, like flying fish, and sometimes squid.

Scientists have spent a long time studying how these birds are related to others. For many years, people thought they were part of the Pelecaniformes group. This group includes pelicans, cormorants, and frigatebirds. However, new studies have changed this idea. In 1995, Konstantin Mikhailov looked at eggshells under a microscope. He found that tropicbird eggshells lacked certain materials found in other birds. Now, research from 2014 shows they are most closely related to the sunbittern and the kagu.

There are three living species in the genus Phaethon.

The red-billed tropicbird lives in the Atlantic, eastern Pacific, and Indian oceans. The red-tailed tropicbird is found in the Indian Ocean and parts of the Pacific. The white-tailed tropicbird lives in many tropical waters, except the eastern Pacific. The red-billed species split from the others about six million years ago. The red-tailed and white-tailed species split about four million years ago. The name Phaethon comes from the Ancient Greek word for "sun."

Life in the colony can be very loud and busy. Tropicbirds make piercing, shrill whistling calls that sound like a crackle. In old books, people called them "boatswain" birds because of these sounds. During courtship, birds fly in large vertical circles together. They swing their long tail streamers from side to side to impress mates.

After mating, the female lays one spotted egg in a hole or crevice. Both parents help care for the chick for about 12 to 13 weeks. Before they fly, young birds float on the ocean to lose weight.
