Cuckoo-roller

Species of bird

The cuckoo-roller or courol (Leptosomus discolor) 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.
