Cuckoo-Roller
The cuckoo-roller is a relic species: the sole living member of the order Leptosomiformes — for comparison, other bird orders can contain hundreds of species, while Passeriformes (a.k.a. songbirds) has over 6,500. And, despite its name, the cuckoo-roller is not closely related to cuckoos nor rollers.
