Nightjars are declining heathland birds whose welfare depends on maintaining lowland heath habitat and managing human disturbance during their sensitive breeding season.
Nightjar welfare during the breeding season is particularly vulnerable to human and dog disturbance because they nest on bare ground and rely on cryptic camouflage for protection. A disturbed nightjar may flush from the nest, exposing eggs or chicks to temperature extremes and predation. Night walkers with dogs off-lead on heathlands cause particular risk. Habitat management that maintains open heathland structure with bare sand patches, scattered heather and scrub provides the conditions nightjars need. Respecting seasonal access restrictions and keeping dogs on leads during the breeding season directly protects nesting welfare.
