Birds are one of only four taxonomic groups to have evolved powered flight. A number of animals are capable of aerial locomotion, either by powered flight or by gliding. This trait has appeared by evolution many times, without any single common ancestor. Flight has evolved at least four times in separate animals: insects, pterosaurs, birds, and ...

Bird flight includes multiple types of motion, including hovering, taking off, and landing, involving many complex movements.
The family gets its scientific name for Latin coracium, "like a raven", and the English name "roller" from the aerial acrobatics some of these birds perform during courtship or territorial flights. [4] The phylogenetic relationship between the six families that make up the order Coraciiformes is shown in the cladogram below.
