The nightingale's famous song fills dense scrub thickets on warm spring nights. With a 90% UK breeding range contraction since 1970, nightingale welfare depends on maintaining young, dense scrubby woodland with deep leaf litter.
Nightingale welfare depends on scrub habitat that is becoming increasingly scarce through several combined pressures: abandonment of hazel coppicing removes the 3-7 year cycle that creates optimal scrub structure; deer overpopulation strips ground cover below knee height; development removes traditional nightingale scrub at woodland edges and brownfield sites. Research shows nightingales at sites with deer exclosures have significantly higher breeding success than adjacent unprotected areas. Traditional coppice management that creates dense young scrub patches within broader woodland is the most welfare-effective habitat management for this species.
