![]() Placement in this family is tentative, it may instead belong to the family Sophiornithidae. Genus Palaeobyas (Late Eocene/Early Oligocene) from Quercy, France. Genus Palaeotyto (Late Eocene/Early Oligocene) from Quercy, France. "TMT 164" (Middle Miocene of Grive-Saint-Alban, France) - Prosybris? Genus Prosybris (Late Eocene/Early Oligocene of Quercy(?) – Early Miocene of France and Austria) Genus Selenornis (Late Eocene/Early Oligocene of Quercy, France) – includes Asio henrici Genus Necrobyas (Late Eocene/Early Oligocene – Late Miocene, France) – includes Bubo arvernensis and Paratyto Genus Nocturnavis (Late Eocene/Early Oligocene) – includes Bubo incertus At least four extinct genera of barn-owls have been described: Two subfamilies are known only from the fossil record: the Necrobyinae and the Selenornithinae. The fossil record of barn-owls goes back to the Eocene, with the family eventually losing ground to the true owls after the radiation of rodents and owls during the Neogene epoch. prigoginei) found in Congo, and Sri Lanka bay owls (P. badius) found in India, Congo bay owls (P. Bay owls have a much smaller distribution than genus Tyto, with Oriental bay owls (P. prigoginei), and the Sri Lanka bay owls (P. This genus includes the Oriental bay owls (P. delicatula) can be found in Australia, New Zealand, Polynesia, and Asia. furcata) can be found from North to South America. alba) can be found in Africa and parts of Asia, including Eurasia. Of the Australian barn owl, there are 4 subspecies: T. Of the American barn owl, there are 5 subspecies: T. Of the common barn owl there are 10 subspecies: T. Within each of these species, there are many subspecies. Some of the Tyto species that exist include the common barn owl (Tyto alba), the American barn owl (Tyto furctata), the Australian barn owl (Tyto delicatula), and the Eastern Barn Owl (T. This map shows the combined distributions of the Genus Tyto. Genus Tyto – true barn-owls, grass owls and masked owls (17 species) This is unsupported by more recent research (see Cypselomorphae), but the relationships of the owls in general are still unresolved. The Sibley-Ahlquist taxonomy unites the Caprimulgiformes with the owl order here, barn-owls are a subfamily, Tytoninae. This discovery led to the finding of Tyto pollens, Tyto noeli, and Tyto riveroi in nearby cave deposits, all of which are now extinct and were also considered giant. The systematics of this group began with the discovery of Tyto ostologa (now extinct), whose remains were found in north-central Haiti. It is believed the modern genus Tyto descended from large nocturnal birds in the West Indies during the Quaternary. The modern genuses Tyto and Phodilus are thought to have originated from a common ancestor from the Oligocene period. Barn-owls are mostly nocturnal and generally non-migratory, living in pairs or singly.īarn-owls consist of two extant subfamilies: the Tytoninae or Tyto owls (including the common barn owl) and the Phodilinae or bay owls. However, some subspecies of the common barn-owl possibly deserve to be separate species, but are very poorly known.įive species of barn-owl are threatened, and some island species went extinct during the Holocene or earlier (e.g., Tyto pollens, known from the fossil record of Andros Island in the Bahamas, and possibly the basis for the mythical chickcharney). Some, like the red owl, have barely been seen or studied since their discovery, in contrast to the common barn-owl, which is one of the best-known owl species in the world. The majority of the 20 living species of barn-owls are poorly known. Within these habitats, they live near agricultural areas with high amounts of human activity. They live in a wide range of habitats from deserts to forests, and from temperate latitudes to the tropics. They also differ from the Strigidae in structural details relating in particular to the sternum and feet.īarn-owls are a wide-ranging family, although they are absent from northern North America, Saharan Africa, and large areas of Asia. They have long, strong legs with powerful talons. They are medium to large owls with large heads and characteristic heart-shaped faces. Barn-owls (family Tytonidae) are one of the two families of owls, the other being the true owls or typical owls, Strigidae. ![]()
