Little Owl Welfare and Conservation in the UK

Welfare and conservation guide for little owls — an introduced species now at risk from farmland habitat loss.

Key Facts

Little owls were introduced to England in the 19th century and are now naturalised and protected
They are diurnal (active during the day) — unlike most owls — making them more susceptible to human disturbance
Little owl populations have declined significantly — linked to loss of rough grassland and old orchards
They nest in tree cavities and old buildings — nest site loss through building renovation is a welfare concern
Little owls rely on invertebrate prey — earthworms, beetles, and small mammals — from short, rough grassland
Nest box provision has significantly contributed to population recovery in some areas
Road mortality and cat predation are individual welfare concerns
Little owls defending nest sites can suffer injury from repeated disturbance by photographers or researchers

Welfare Significance

Little owl welfare is primarily linked to landscape quality — availability of rough grassland with invertebrate prey, and nest cavities for breeding. The welfare of individual birds at nest sites is also important — excessive disturbance during the breeding season can cause nest failure and parental distress. Sensitive management of known nest sites is essential.

What You Can Do

Erect little owl nest boxes in suitable farmland and orchard habitats
Avoid disturbing known little owl nest sites during the breeding season (March-July)
Maintain rough grassland and old orchards to support invertebrate prey availability
Report little owl sightings and nest sites to local ornithological societies
