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.

These are medium-sized to large, robustly built, powerful owls. They do not have ear tufts and most are highly nocturnal woodland birds. Most prey on small mammals, birds, and reptiles.

Most owls in the genus Strix can be distinguished from other genera of owls through their hooting vocalization and lack of visible ears.

The Latin genus name Strix referred to a mythical vampiric owl-monster believed to suck the blood of infants. [2] Although the genus Strix was established for the earless owls by Linnaeus in 1758, many applied the term to other owls (namely the Tyto ) until the late 19th century. [3] This genus is closely related to the extinct Ornimegalonyx.

Taxonomy

The genus Strix was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae . [4] The type species is the tawny owl. [5] The genus name is a Latin word meaning "owl". [6]

Species

The genus contains 22 species: [7]

Fossil species

The genus Strix is well represented in the fossil record. [3] Being a fairly generic type of strigid owl, they were probably the first truly modern Strigidae to evolve. However, whether several of the species usually placed in this genus indeed belong here is uncertain.

Generally accepted in Strix are:

"Strix" wintershofensis (Early/Middle Miocene of Wintershof West, Germany) and "Strix" edwardsi (Middle Miocene of Grive-Saint-Alban, France), while being strigid owls, have not at present been reliably identified to genus; they might also belong into the European Ninox-like group.[ citation needed ]

"Strix" ignota (Middle Miocene of Sansan, France) is sometimes erroneously considered a nomen nudum , but this assumption is based on what appears to be a lapsus or misprint in a 1912 source. [8] It may well belong into the present genus, but this requires confirmation. [3]

"Strix" perpasta (Late Miocene – Early Pliocene of Gargano Peninsula, Italy) does not appear to belong into this genus either. [9] It is sometimes considered a junior synonym of a brown fish-owl paleosubspecies. [3]

UMMP V31030, a coracoid from Late Pliocene Rexroad Formation deposits of Kansas (USA), cannot be conclusively assigned to either the present genus or Bubo . [10]

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.

<span class="mw-page-title-main">Falcon</span> Birds of prey in the genus Falco

Falcons are birds of prey in the genus Falco, which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene.

<span class="mw-page-title-main">True owl</span> Family of birds

The true owls or typical owls are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica.

<span class="mw-page-title-main">Barn-owl</span> Family of birds

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.

<span class="mw-page-title-main">Horned owl</span> Genus of birds (Bubo)

The American horned owls and the Old World eagle-owls make up the genus Bubo, at least as traditionally described. The genus name Bubo is Latin for owl.

<i>Larus</i> Genus of birds

Larus is a large genus of gulls with worldwide distribution.

<i>Tringa</i> Genus of birds

Tringa is a genus of waders, containing the shanks and tattlers. The genus name Tringa is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1599. They are mainly freshwater birds, often with brightly coloured legs as reflected in the English names of six species, as well as the specific names of two of these and the green sandpiper. They are typically associated with northern hemisphere temperate regions for breeding. Some of this group—notably the green sandpiper—nest in trees, using the old nests of other birds, usually thrushes.

<span class="mw-page-title-main">Eurasian scops owl</span> Species of owl

The Eurasian scops owl, also known as the European scops owl or just scops owl, is a small owl in the typical owl family Strigidae. Its breeding range extends from southern Europe eastwards to southern Siberia and the western Himalayas. It is migratory, wintering in Africa south of the Sahara.

<i>Columba</i> (bird) Genus of pigeons

The bird genus Columba comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon, some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon.

<i>Anas</i> Genus of birds

Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".

<span class="mw-page-title-main">Scops owl</span> Genus of birds

Scops owls are typical owls in family Strigidae belonging to the genus Otus and are restricted to the Old World. Otus is the largest genus of owls with 59 species. Scops owls are colored in various brownish hues, sometimes with a lighter underside and/or face, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a greyish- and a reddish-brown morph. They are small and agile, with both sexes being compact in size and shape. Female scops owls are usually larger than males.

<i>Tyto</i> Genus of birds

Tyto is a genus of birds consisting of true barn owls, grass owls and masked owls that collectively make up all the species within the subfamily Tytoninae of the barn owl family, Tytonidae.

<i>Asio</i> Genus of birds

Asio is a genus of typical owls, or true owls, in the family Strigidae. This group has representatives over most of the planet, and the short-eared owl is one of the most widespread of all bird species, breeding in Europe, Asia, North and South America, the Caribbean, Hawaii and the Galápagos Islands. Its geographic range extends to all continents except Antarctica and Australia.

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

Ardea is a genus of herons. These herons are generally large in size, typically 80–100 cm or more in length.

<i>Ninox</i> Genus of birds

Ninox is a genus of true owls comprising 36 species found in Asia and Australasia. Many species are known as hawk-owls or boobooks, but the northern hawk-owl is not a member of this genus.

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

Pavo is a genus of two species in the pheasant family. The two species, along with the Congo peafowl, are known as peafowl.

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

Athene is a genus of owls, containing nine living species, depending on classification. These birds are small, with brown and white speckles, yellow eyes, and white eyebrows. This genus is found on all continents except for Australia, Antarctica, and Sub-Saharan Africa. An evolutionary radiation of 4 species is also present in the Solomon Islands.

<i>Tetrao</i> Genus of birds

Tetrao is a genus of birds in the grouse subfamily known as capercaillies. They are some of the largest living grouse. Feathers from the bird were used to create the characteristic hat of the bersaglieri, an Italian ace infantry formation.

<span class="mw-page-title-main">Tawny owl</span> Stocky medium-sized owl species

The tawny owl, also called the brown owl, is commonly found in woodlands across Europe to western Siberia, and has seven recognized subspecies. It is a stocky, medium-sized owl, whose underparts are pale with dark streaks, and whose upper body may be either brown or grey. The tawny owl typically makes its nest in a tree hole where it can protect its eggs and young against potential predators. It is non-migratory and highly territorial: as a result, when young birds grow up and leave the parental nest, if they cannot find a vacant territory to claim as their own, they will often starve.

<span class="mw-page-title-main">Taxonomy of the tawny owl</span>

The species was first described by Linnaeus in his Systema naturae in 1758 under its current scientific name. The binomial derives from Greek strix "owl" and Italian allocco, "tawny owl". Some early descriptions upon review were found to have somehow conflated the very different barn owl with the scientific name Strix aluco, which in turn engendered some confusion.
