Ural owl
The Ural owl (Strix uralensis) is a large, nocturnal true owl belonging to the genus Strix, named after the Ural Mountains where its type specimen was collected. It boasts an extensive Palearctic distribution, inhabiting taiga and other forest types, and is distinguished by its pale greyish-brown plumage, long tail, and dark brown eyes. This species is primarily a dietary generalist, heavily relying on small mammals, especially rodents like voles.

About Ural owl
The Ural owl (Strix uralensis) is a large, nocturnal owl belonging to the true owl family, Strigidae, and the genus Strix. Its common and scientific names are derived from the Ural Mountains in Russia, where the type specimen was collected. However, this species possesses an exceptionally broad distribution across the Palearctic, extending from Scandinavia and eastern Europe eastward through Russia to Sakhalin and Japan.
Description and Habitat
This forest owl is typically found in the vast taiga forests of Eurosiberia, but it also inhabits mixed and temperate deciduous forests. Physically, the Ural owl is characterized by a broad, rounded head, a correspondingly round facial disc, and a notably long tail. Its plumage is generally a plain pale greyish-brown to whitish, with darker grey-brown upperparts featuring whitish markings. The underparts are pale cream-ochre to grey-brown, adorned with bold dark brown streaking. Notable features include a buffish-white underwing with heavy dark bars and a long, white-tipped tail. The eyes are a distinctive dark brown. Adult Ural owls range from 50 to 64 cm in length, with a wingspan of 110 to 134 cm. Females are typically slightly larger than males.
Diet and Behavior
Like many owls in the Strix genus, the Ural owl is a dietary generalist, though it commonly relies on small mammals, especially small rodents like voles. They are territorial birds that vigorously defend their nesting areas. Reproductive success is often closely tied to the availability of prey populations. While generally nocturnal, they have been noted to exhibit some diurnal behavior during warmer months, leading to potential confusion with other birds of prey.
Vocalizations and Conservation
The song of the male Ural owl is a deep, rhythmic series of notes, while the female's is similar but hoarser. They also employ contact calls and begging calls by juveniles. The species is generally considered quiet for a large owl. The Ural owl is classified by the IUCN as a species of Least Concern, indicating a stable population overall, though reintroduction efforts have aided its presence in some parts of central Europe.
Taxonomy and Relatives
The Ural owl is part of the Strix genus, which includes other well-known owls like the tawny owl (Strix aluco). Fossil evidence suggests a complex evolutionary history within the genus. Some authors consider the Père David's owl (Strix davidi) to be either an isolated subspecies or a distinct species within the Strix complex, with debate continuing based on morphological, vocal, and genetic studies. The barred owl (Strix varia) in North America is also considered closely related, with some early classifications even grouping them within a species complex.
