Cuckoo-roller

Common card · No. 446594

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. It is a medium-large bird, inhabiting 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 Grande Comore. 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 Comoros cuckoo-roller (L. gracilis).
