Kestrel Nest Box Schemes and Farmland Welfare

Kestrel populations have declined by over 50% since the 1970s - nest box schemes and farmland habitat restoration offer key welfare and conservation benefits.

Key Facts

UK kestrel numbers have declined by around 50% since 1970 due to agricultural intensification
Kestrels depend on rough grassland for hunting small mammals, especially voles
Loss of field margins, roadside verges, and grassland has reduced prey availability
Kestrels naturally nest in tree holes, cliff ledges, and old buildings - nest sites can be limiting
Nest box schemes on farms and alongside motorways have helped stabilise some populations
Kestrels are a key indicator species for farmland ecosystem health

Welfare Considerations

Kestrel welfare is closely tied to prey availability and nest site access. Birds in poor condition from food scarcity are more susceptible to cold stress, disease, and predation. Agricultural intensification has removed the rough grassland habitat that supports vole populations on which kestrels depend. Restoring field margins, managing verges for tall grass, and installing nest boxes directly improves kestrel welfare. The species' iconic status makes it a powerful ambassador for farmland wildlife conservation more broadly.

What You Can Do

Install a kestrel nest box on suitable farm buildings, barns, or tall poles in open countryside
Maintain or advocate for rough grass strips and field margins on farmland
Report kestrel sightings to the BTO BirdTrack recording scheme
Support campaigns for agri-environment scheme payments for kestrel-friendly farmland management
Engage with your local wildlife trust on kestrel monitoring and box scheme participation
Reduce pesticide use that reduces invertebrate and small mammal prey populations
