Nightingales have declined by 90% in Britain over 50 years due to loss of dense scrub and coppice woodland that provides optimal nesting and feeding habitat.
Nightingale decline reflects systematic habitat loss across their limited UK range. Males arriving from Africa to find adequate territory increasingly must attempt breeding in suboptimal habitat or fail to breed. Individual welfare is compromised by exhausting migration followed by inadequate breeding conditions. Conservation of remaining scrub habitats and restoration of coppice woodland with deer management directly supports individual nightingale welfare by maintaining the conditions necessary for successful breeding. Each restored hectare of suitable habitat represents welfare benefit for multiple individuals over multiple breeding seasons.
