Tyto gigantea is an extinct barn owl from what is now Gargano, Italy, dating back to the late Miocene. From its remains, T. gigantea is suggested to have been as large as or larger than the Eurasian eagle-owl (Bubo bubo).

This species seems to have lived at the same time as the closely related owl, Tyto robusta . [1] That would represent a single lineage of owls adapting to the largest size of their prey on the island, such as the great erinaceomorph of Gargano, Deinogalerix , and rodents. [2]

Owls are birds from the order Strigiformes, which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl.

Barn-owls are one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the Strigidae in structural details relating in particular to the sternum and feet.

The Eurasian eagle-owl is a species of eagle-owl that resides in much of Eurasia. It is also called the Uhu and it is occasionally abbreviated to just the eagle-owl in Europe. It is one of the largest species of owl, and females can grow to a total length of 75 cm (30 in), with a wingspan of 188 cm, with males being slightly smaller. This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish colouring and tawny. The wings and tail are barred. The underparts are a variably hued buff, streaked with darker colouring. The facial disc is not very defined and the orange eyes are distinctive.

<span class="mw-page-title-main">Barn owl</span> Common cosmopolitan owl species

The barn owl is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, being found almost everywhere except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls (Strigidae).

Gargano is a historical and geographical sub-region in the province of Foggia, Apulia, southeast Italy, consisting of a wide isolated mountain massif made of highland and several peaks and forming the backbone of the Gargano Promontory projecting into the Adriatic Sea, the "spur" on the Italian "boot". The high point is Monte Calvo at 1,065 m (3,494 ft). Most of the upland area, about 1,200 km2 (460 sq mi), is part of the Gargano National Park, founded in 1991. In this region since 1978 a feud has been fought between the clans of the Società foggiana.

<i>Strix</i> (bird) Genus of birds

Strix is a genus of owls in the typical owl family (Strigidae), one of the two generally accepted living families of owls, with the other being the barn-owl (Tytonidae). Common names are earless owls or wood owls, though they are not the only owls without ear tufts, and "wood owl" is also used as a more generic name for forest-dwelling owls. Neotropical birds in the genus Ciccaba are sometimes included in Strix.

<i>Deinogalerix</i> Extinct genus of mammals

Deinogalerix is an extinct genus of gymnure which lived in Italy in the Late Miocene, 7-10 million years ago. The genus was apparently endemic to what was then the island of Gargano, which is now a peninsula. The first specimens of Deinogalerix were first described in 1972.

The Cuban giant owl or giant cursorial owl (Ornimegalonyx) is an extinct genus of giant owl that measured 1.1 metres in height. It is closely related to the many species of living owls of the genus Strix. It was a flightless or nearly flightless bird and it is believed to be the largest owl that ever existed. It lived on the island of Cuba.

Whitaker's shrew is a species of mammal in the family Soricidae. It is found in Western Sahara, Algeria, Morocco, Tunisia. Its natural habitats are subtropical or tropical dry shrubland, rocky and sandy coasts. It is a fairly common species and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".

<i>Tyto robusta</i> Extinct species of bird

Tyto robusta was a prehistoric barn-owl. It lived at what is now Monte Gargano in Italy, and was an island throughout much of the Neogene when sea levels were higher. The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago. The fossil bones are about 60% as long again as a modern barn owl, giving a total length of about 50–65 cm for T. robusta. This owl provides an interesting case study of evolution and insular gigantism.

Garganornis is an extinct genus of enormous flightless anatid waterfowl from the Late Miocene of Gargano, Italy. The genus contains one species, G. ballmanni, named by Meijer in 2014. Its enormous size is thought to have been an adaptation to living in exposed, open areas with no terrestrial predators, and as a deterrent to the indigenous aerial predators like the eagle Garganoaetus and the giant barn owl Tyto gigantea.

Rivero's barn owl is an extinct species of barn owl that was very large — bigger than any extant barn owl species, and possibly larger than any known owl alive today. It is thought to have been nearly as large as another extinct gigantic owl, Ornimegalonyx. Suárez and Olson demoted T. riveroi as a junior synonym of Tyto pollens in 2015.
