There are 13 species in the Coraciidae family. These colorful birds are found in warm parts of Europe, Asia, Africa, and Australia.

Rollers are about the size of a crow. They have strong bills, medium-to-long tails, and feet with two front toes partly joined. Many species have blue, turquoise, brown, and purple feathers.

Rollers get their name from their courtship flights. During these displays, they soar into the air, dive toward the ground, and perform twists and rolls before climbing back up.

These birds feed mainly on insects, but they also eat small reptiles, frogs, and other small animals. They often hunt from a perch, watching for prey before swooping down to catch it. Some species also catch insects while flying.
