Approximately 202 species of owls comprise the distinctive cosmopolitan neoavian Order Strigiformes. All morpho- logical and genetic studies agree that the order is a natural group. Two families are recognized: Tytonidae (barn owls and bay owls) and Strigidae (typical owls). The strigiform timetree shows that these families are ancient, having diverged in the late Cretaceous 71 million years ago (Ma).
