Little Owl (Athene noctua) lives in open woodland across Europe, Asia, North Africa. It feeds on insects and worms. Its conservation status is Least Concern.

A real field recording of the Little Owl, made in the wild.
A tiny predator, the little owl measures just 22 cm (8.7 in) long with a 56 cm (22 in) wingspan and tips the scales at roughly 180 g (6.3 oz). Yet individuals can range from a feather-light 98 g up to a hefty 280 g in the wild, while captive birds have been recorded at 350 g.
Territorial little owls shrink their hunting grounds: in diverse farmland they defend less than 2 ha, but on uniform fields their range can exceed 12 ha. Across the year their home-range swings dramatically, from as tiny as 1.8 ha to a sprawling 95 ha, with an average of 15.1 ha (0.151 km²). Smaller territories mean shorter flights and more frequent nest visits, while larger ones force longer foraging trips.
In the wild a little owl can live up to 15 years 7 months, but most only reach about 4 years, with an average expectancy of 16 years skewed by severe winters and road deaths that pull the mean down to roughly 3 years. Adult mortality runs 24.2-39 % per year, while juveniles face a grim 69-94 % chance of dying before adulthood.
Air-quality monitors have unintentionally become biodiversity samplers: filters from a London sensor and one at Auchencorth Moss in Scotland yielded DNA that confirmed the presence of little owls among more than 180 taxa of mammals, plants, birds and invertebrates. This discovery shows that existing pollution-sensor networks could provide high-frequency, non-invasive snapshots of owl distribution without any extra fieldwork, opening a new frontier for tracking even cryptic species.
A pellet analysis revealed that mammals make up 20-50 % of the little owl's diet, while insects contribute 24-49 %. The mammals include mice, rats, voles, squirrels, shrews, moles and even rabbits.

As the sun dips below the horizon, the little owl stirs, its piercing gaze scanning the landscape with an unblinking intensity, its soft, feathery plumage a masterful disguise as it slips silently into the gathering dusk. With wings that beat in a slow, deliberate rhythm, it navigates the twilight world with ease, its acute hearing and exceptional night vision guiding it through the shadows in search of unsuspecting prey. In this crepuscular realm, the little owl reigns supreme, a diminutive yet formidable monarch of the nocturnal landscape.
