Little Owl Farmland Welfare and Agricultural Change

The little owl has declined significantly across Britain as agricultural intensification reduces invertebrate prey and removes traditional nest sites in old trees and farm buildings.

Key Facts

UK little owl numbers have declined by around 43% since 1970
They require short grassland or bare ground with high earthworm and beetle availability
Old hedgerow trees, stone walls, and farm buildings are traditional nest sites
Pesticide use reduces the invertebrate prey base critical for chick rearing
Cold, wet springs with low invertebrate activity cause high chick mortality

Welfare Considerations

Little owls in degraded agricultural landscapes experience welfare challenges from reduced prey availability and loss of nest sites. Birds in territories with poor invertebrate availability must range further and with greater effort, particularly during chick rearing when food demand is highest. Cold, wet spring weather suppresses invertebrate activity at the critical chick-growth period, causing starvation stress in affected nests. The loss of old trees and farm buildings removes nest cavities that take decades to regenerate.

What You Can Do

Install little owl nest boxes on farmland at 2-4m height in trees or buildings
Maintain rough, short grassland habitats with diverse invertebrate communities
Reduce insecticide use and support invertebrate-rich habitat management
Report little owl sightings to BTO Breeding Bird Survey and Atlas surveys
Advocate for agri-environment scheme payments for rough grassland maintenance
