Wild Nightjar Conservation and Heathland Welfare

Nightjars are summer migrants to British heathland that face habitat loss and disturbance threats during their breeding season.

Key Facts

Nightjar populations increased by approximately 50% in the UK between 1981 and 2004 but remain restricted
They require open heathland and young forestry plantations with bare ground for nesting
Nightjars are ground nesters with cryptic camouflage - they are easily disturbed by walkers and dogs
Their distinctive churring call is the primary method of monitoring population status
They feed exclusively on moths and beetles caught in aerial pursuit at dusk and dawn
Climate change may affect moth emergence timing relative to nightjar breeding requirements
Nest disturbance causes desertion - adults flush from nests only under significant pressure
Nightjars are Schedule 1 protected species - deliberate disturbance at the nest is a criminal offence

Welfare Considerations

Nightjar welfare during breeding is most threatened by nest disturbance from recreational use of heathland. Ground-nesting birds repeatedly flushed from nests experience significant stress and lose thermoregulation time for eggs and chicks. Dogs off leads are a particular threat as they can locate and disturb nests that humans walk past without noticing. The cryptic plumage of nightjars means nests are easily destroyed by trampling. Access management on heathland during the nightjar breeding season (May to August) directly protects individual welfare.

What You Can Do

Keep dogs on leads when walking on heathland between May and August
Stick to marked paths on heathland - the surrounding ground may contain nightjar nests
Visit nightjar sites at dusk to listen for churring calls rather than searching for nesting birds
Support the RSPB and Wildlife Trusts managing heathland for nightjar breeding
Advocate for access management signage and seasonal dog-lead requirements on key heathland sites
