Carine noctua

The little owl (Athene noctua) is a bird that inhabits much of the temperate and warmer parts of Europe, Asia east to Korea, and north Africa. It was introduced into the British Isles at the end of the nineteenth century and into the South Island of New Zealand in the early twentieth century.

It 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, 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 which 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.

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

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.[2] It is usually 22 centimetres (8.7 in) in length with a wingspan of 56 centimetres (22 in) for both sexes, and weighs about 180 grams (6.3 oz).[3]

The adult little owl of the most widespread form, the nominate A. n. noctua, is white-speckled brown above, and brown-streaked white below. It has a large head, long legs, and yellow eyes, and its white “eyebrows” give it a stern expression. Juveniles are duller, and lack the adult's white crown spots. This species has a bounding flight like a woodpecker but the rounded wingtips and general appearance of the birds are quite different.[2]

The call is a querulous kiew, kiew. Less frequently, various whistling or trilling calls are uttered. In the breeding season, other more modulated calls are made, and a pair may call in duet. Various yelping, chattering or barking sounds are made in the vicinity of the nest.[2]

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.[4]

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.[4]

There are thirteen recognized subspecies of little owl spread across Europe and Asia.[5]

  • A. n. noctua (Scopoli, 1769): from central, southern and south-eastern Europe to north-western Russia.
  • A. n. bactriana (Blyth, 1847): from Iraq and Azerbaijan to Pakistan and north-western India.
  • A. n. glaux (Savigny, 1809): from the coast of north Africa to south-western Israel.
  • A. n. impasta (Bangs & Peters, 1928): central-west China.
  • A. n. indigena (Brehm, 1855): from Ukraine and Romania to Greece and Turkey and southern Russia.
  • A. n. lilith (Hartert, 1913): from Cyprus and southern Turkey to Iraq and Sinai Peninsula (Egypt).
  • A. n. ludlowi (Baker, 1924): Himalayas.
  • A. n. orientalis (Severetzov, 1873): north-eastern Kazakhstan and north-western China.
  • A. n. plumipes (Swinhoe, 1870): Mongolia, southern Siberia and north-eastern China.
  • A. n. saharae (Kleinschmidt, 1909): from Morocco to western Egypt and central Arabia.
  • A. n. somaliensis (Reichenow, 1905): eastern Ethiopia and Somalia.
  • A. n. spilogastra (von Heuglin, 1863): eastern Sudan, Eritrea and north-eastern Ethiopia.
  • A. n. vidalii (Brehm 1857): western Europe.

The little owl was sacred to the goddess Athena, from whom it gets the generic name.[3]

Distribution and habitat

The little owl has a widespread distribution across Europe, Asia and North Africa. Its range in Eurasia extends from the Iberian Peninsula and Denmark eastwards to China and southwards to the Himalayas. In Africa it is present from Mauritania to Egypt, the Red Sea and Arabia. The bird has been introduced to New Zealand, and to the United Kingdom, where it has spread across much of England and the whole of Wales.[6]

This is a sedentary species which is found in open countryside in a great range of habitats. These include agricultural land with hedgerows and trees, orchards, woodland verges, parks and gardens, as well as steppes and stony semi-deserts. It is also present in treeless areas such as dunes, and in the vicinity of ruins, quarries and rocky outcrops. It sometimes ventures into villages and suburbs. In the United Kingdom it is chiefly a bird of the lowlands, and usually occurs below 500 m (1,600 ft).[2] In continental Europe and Asia it may be found at much higher elevations; one individual was recorded from 3,600 m (12,000 ft) in Tibet.[7]

Behaviour and ecology

The little owl usually perches in an elevated position ready to swoop down on any small creature it notices. It feeds on prey such as insects and earthworms, as well as small vertebrates including amphibians, reptiles, birds and mammals. It may pursue prey on the ground and it caches surplus food in holes or other hiding places.[6] A study of the pellets of indigestible material that the birds regurgitate found mammals formed 20 to 50% of the diet and insects 24 to 49%. Mammals taken included mice, rats, voles, shrews, moles and rabbits. The birds were mostly taken during the breeding season and were often fledglings, and including the chicks of game birds. The insects included Diptera, Dermaptera, Coleoptera, Lepidoptera and Hymenoptera. Some vegetable matter (up to 5%) was included in the diet and may have been ingested accidentally.[2]

The little owl is territorial, the male normally remaining in one territory for life. However the boundaries may expand and contract, being largest in the courtship season in spring. The home range, in which the bird actually hunts for food, varies with the type of habitat and time of year. If a male intrudes into the territory of another, the occupier approaches and emits its territorial calls. If the intruder persists, the occupier flies at him aggressively. If this is unsuccessful, the occupier repeats the attack, this time trying to make contact with his claws. In retreat, an owl often drops to the ground and makes a low-level escape.[8] The territory is more actively defended against a strange male as compared to a known male from a neighbouring territory; it has been shown that the little owl can recognise familiar birds by voice.[9]

This owl becomes more vocal at night as the breeding season approaches in late spring. The nesting location varies with habitat, nests being found in holes in trees, in cliffs, quarries, walls, old buildings, river banks and rabbit burrows.[7] A clutch of three to five eggs is laid (occasionally two to eight). The eggs are broadly elliptical, white and without gloss; they measure about 35.5 by 29.5 mm (1.40 by 1.16 in). They are incubated by the female who sometimes starts sitting after the first egg is laid. While she is incubating the eggs, the male brings food for her. The eggs hatch after twenty-eight or twenty-nine days.[2] At first the chicks are brooded by the female and the male brings in food which she distributes to them. Later, both parents are involved in hunting and feeding them. The young leave the nest at about seven weeks, and can fly a week or two later. Usually there is a single brood but when food is abundant, there may be two.[6] When the young disperse, they seldom travel more than about 20 kilometres (12 mi).[4] Pairs of birds often remain together all year round and the bond may last until one partner dies.[4]

The little owl is partly diurnal and often perches boldly and prominently during the day.[7] If living in an area with a large amount of human activity, little owls may grow used to humans and will remain on their perch, often in full view, while people are around. The little owl has a life expectancy of about sixteen years.[6] However, many birds do not reach maturity; severe winters can take their toll and some birds are killed by road vehicles at night,[6] so the average lifespan may be in the order of three years.[3]


The little owl has an extremely large range. It has been estimated that there are between 560 thousand and 1.3 million breeding pairs in Europe, and as Europe equates to 25 to 49% of the global range, the world population may be between five million and fifteen million birds. The population is believed to be stable, and for these reasons, the International Union for Conservation of Nature has assessed the bird's conservation status as being of "least concern".[1]

In human culture

Owls have often been depicted from the Upper Palaeolithic onwards, in forms from statuettes and drawings to pottery and wooden posts, but in the main they are generic rather than identifiable to species. The little owl is however closely associated with the Greek goddess Athena and the Roman goddess Minerva, and hence represents wisdom and knowledge. A little owl with an olive branch appears on a Greek tetradrachm coin from 500 B.C. and in a 5th century B.C. bronze statue of Athena holding the bird in her hand. The call of a little owl was thought to have heralded the murder of Julius Caesar.[10][11]
