Wild Little Owl Welfare: An Introduced Species Facing Modern Pressures

The little owl, introduced to Britain in the 19th century, is now a declining resident that faces welfare challenges from agricultural intensification and loss of rough grassland habitat.

Key Facts

Little owls were introduced to Britain from the Netherlands in the 1870s and 1880s and are now naturalised
The UK population is estimated at around 5,700 pairs but has declined by approximately 24% since 1995
The species favours lowland farmland with old trees, orchards, and rough grassland margins
Little owls feed primarily on earthworms, beetles, and small vertebrates; changes in land use affect prey availability
They nest in tree cavities, old buildings, and nest boxes; loss of veteran trees reduces natural nest sites
Rough, tussocky grassland is critical for hunting; agricultural improvement removes this habitat
The species is on the Amber List in the UK Bird Conservation Status review
Nest box schemes have proven effective at supporting little owl populations in some areas

Welfare Considerations

The little owl's welfare challenges stem from the broader impoverishment of lowland farmland. The loss of traditional orchards, veteran trees, and rough grassland has reduced both nesting and foraging opportunities. Individual birds hunting over intensively managed fields face poorer prey availability and must work harder to meet their energetic needs. Supporting the retention of old trees and traditional orchard habitats, and encouraging rough grassland margins on farms, directly benefits little owl welfare and the many other species that share these habitats.

What You Can Do

Support traditional orchard conservation projects run by wildlife organisations
Encourage landowners to install little owl nest boxes in suitable habitat
Avoid the removal of old trees and veteran trees on your land or in your community
Support agri-environment schemes that maintain rough grassland and traditional farmland features
Record and report little owl sightings to local wildlife groups and the BTO
