The cuckoo-roller or courol is the only bird in the family Leptosomidae, which was previously often placed in the order Coraciiformes but is now placed in its own order Leptosomiformes. The cuckoo-roller is at the root of a group that contains the Trogoniformes, Bucerotiformes, Piciformes, and Coraciiformes. Despite its name, the cuckoo-roller does not share close evolutionary origins with cuckoos or rollers, although for long it was counted among the closer relatives of the latter.
