Nightjar Heathland Welfare and Light Pollution

Nightjars are nocturnal heathland specialists whose welfare depends on intact heathland habitat and low levels of artificial light pollution.

Key Facts

Nightjars nest on bare ground and depend on moths and other large insects
UK nightjar populations have recovered since 1980s but remain restricted to heathland and clearfell
Artificial light at night disrupts insect abundance and nightjar foraging behaviour
Heathland is one of the UK's most threatened habitats, with 80% lost since 1800

Welfare Considerations

Light pollution reduces prey availability and disrupts the circadian rhythms on which nocturnal foraging depends. Habitat fragmentation limits the ability of nightjars to find mates and establish territories.

What You Can Do

Advocate for dark sky designation around key nightjar heathland sites
Support heathland restoration charities and work parties
Reduce artificial light spillage near sensitive heathland habitats
