Nightjars are enigmatic heathland birds that have declined significantly due to habitat loss - targeted heathland management creates the open, insect-rich habitats they require for breeding success.
Nightjar welfare depends on the availability of open, insect-rich heathland habitat. Habitat management that creates structural diversity - open bare areas for nesting, dense heather for refuge, and insect-productive areas for foraging - directly supports welfare. Dog disturbance is a particular welfare concern as nightjars nest on the ground and can be easily flushed by dogs running off-lead in breeding areas. A disturbed nightjar abandoning eggs or chicks experiences welfare harm and reproductive failure. Keeping dogs on leads on heathlands from May to August significantly reduces this welfare risk. Heathland restoration expanding suitable habitat is the most impactful long-term welfare intervention.
