Little owl

The little owl (Athene noctua), also known as the owl of Athena or owl of Minerva, is a bird that inhabits much of the temperate and warmer parts of Europe, the Palearctic east to Korea, and North Africa. It was introduced into Britain at the end of the 19th century and into the South Island of New Zealand in the early 20th century.

This owl is a member of the typical or true owl family Strigidae, which contains most species of owl, the other grouping being the barn owls, Tytonidae. It is a small (approx. 22 cm long), cryptically coloured, mainly nocturnal species and is found in a range of habitats including farmland, woodland fringes, steppes and semi-deserts. It feeds on insects, earthworms, other invertebrates and small vertebrates. Males hold territories that they defend against intruders. This owl is a cavity nester, and a clutch of about four eggs is laid in spring. The female does the incubation and the male brings food to the nest, first for the female and later for the newly hatched young. As the chicks grow, both parents hunt and bring them food, and the chicks leave the nest at about seven weeks of age.

Being a common species with a wide range and large total population, the International Union for Conservation of Nature has assessed its conservation status as "least concern".

The little owl was formally described in 1769 by the Italian naturalist Giovanni Antonio Scopoli under the binomial name Strix noctua. The little owl is now placed in the genus Athene that was introduced by the German zoologist Friedrich Boie in 1822. The owl was designated as the type species of the genus by George Robert Gray in 1841. The genus name, Athene, commemorates the Greek goddess Athena (whose name is also at times spelled Athene), as the owl was a symbol of wisdom. The species name noctua has, in effect, the same meaning, being the Latin name of an owl sacred to Minerva, Athena's Roman counterpart.

The little owl is probably most closely related to the spotted owlet (Athene brama). A number of variations occur over the bird's wide range, and there is some dispute over their taxonomy. The most distinct is the pale grey-brown Middle-Eastern type known as the Syrian little owl (A. n. lilith). A 2009 paper in the ornithological journal Dutch Birding (vol. 31: 35–37, 2009) has advocated splitting the southeastern races as a separate species, Lilith's owl (Athene glaux), with subspecies A. g. glaux, A. g. indigena, and A. g. lilith. DNA evidence and vocal patterns support this proposal.

Other forms include another pale race, the north African A. n. desertae, and three intermediate subspecies, A. n. indigena of southeast Europe and Asia Minor, A. n. glaux in north Africa and southwest Asia, and A. n. bactriana of central Asia. Differences in size of bird and length of toes, reasons put forward for splitting off A. n. spilogastra, seem inconclusive; A. n. plumipes has been claimed to differ genetically from other members of the species and further investigation is required. In general, the different varieties both overlap with the ranges of neighbouring groups and intergrade (hybridise) with them across their boundaries.

Thirteen subspecies are recognised:

The little owl is a small owl with a flat-topped head, a plump, compact body and a short tail. The facial disc is flattened above the eyes giving the bird a frowning expression. The plumage is greyish-brown, spotted, streaked and barred with white. The underparts are pale and streaked with darker colour. It is usually 22 cm (8.7 in) in length with a wingspan of 56 cm (22 in) for both sexes, and weighs about 180 g (6.3 oz).
