The little owl (Athene noctua) 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 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).
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.
