The family Coraciidae, belonging to the order Coraciiformes, comprises the rollers, a group of colorful, medium-sized birds found mainly in the Old World, including Africa, Europe, and Asia. Rollers are known for their bright plumage—often blues, greens, and browns—and their acrobatic flight displays, particularly during courtship. They have strong, slightly hooked bills adapted for catching insects and small vertebrates, which make up the bulk of their diet. Coraciids typically nest in tree cavities or abandoned burrows and are territorial during the breeding season. Ecologically, they play an important role as insectivores, helping to regulate insect populations across their habitats.
