Nightjar Conservation: Heathland Welfare and Disturbance

Nightjars are specialist heathland birds with highly specific habitat requirements, and their welfare depends on sympathetic management of open heathland and reduction of human disturbance at sensitive breeding sites.

Key Facts

UK nightjar populations are estimated at around 7,000 churring males, mainly in southern England
Nightjars breed on bare ground in heathland, clear-fell forestry and acid grassland habitats
Males produce the distinctive churring call from May to August, particularly at dusk and dawn
Dog disturbance and recreational pressure at breeding sites causes nest abandonment and chick mortality
Habitat management including heather cutting, bracken control and birch removal benefits nightjars
Climate change may benefit nightjars in the short term by extending warm nights favourable for foraging

Welfare Considerations

Nightjar welfare during the breeding season is highly sensitive to disturbance. Ground-nesting birds that rely on camouflage rather than flight as their primary defence are extremely vulnerable to predation and nest abandonment when disturbed by dogs, people or vehicles. A flushed nightjar off her eggs on a cold night risks chick mortality from chilling. Dogs running through heathland during the breeding season can destroy multiple nests in a single visit. Sympathetic visitor management at key nightjar sites - including seasonal path closures and dog leads in sensitive areas - directly reduces welfare harm to breeding birds.

What You Can Do

Keep dogs on leads on heathland during the May-August nightjar breeding season
Follow visitor guidance at designated nightjar sites and nature reserves
Support heathland conservation volunteering including bracken clearance and heather management
Join dusk walks organised by Wildlife Trusts and RSPB to experience nightjars responsibly
