Cuckoo roller

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.
It is a medium-large bird, living in forests and woodlands in Madagascar and the Comoro Islands. Three subspecies are described: the nominate "L. d. discolor" is found in Madagascar and Mayotte Island, "L. d. intermedius" on Anjouan, and "L. d. gracilis" of Grand Comoro. Based on its smaller size, differences in the plumage, and minor difference in the voice, the last of these is sometimes considered a separate species, the Comoro cuckoo roller ("L. gracilis").
