The population of nightingales in England has drastically declined, with numbers falling by approximately 90% from 1967 to 2022. Researchers from the British Trust for Ornithology discovered that English nightingales prefer to isolate themselves in a specific area of Gambia, which has faced severe droughts, instead of spreading across a wider region as European nightingales do. This isolation leaves them particularly vulnerable to climate change and habitat loss. This study sheds light on the stark differences in winter behavior between English and European nightingales, explaining the latter's healthier populations.
The English nightingale is suffering due to its preference for isolation during winter, making it vulnerable to climate and habitat changes in Africa.
British nightingales rarely mix with their European counterparts on their wintering grounds, which may explain their significant decline compared to other European populations.
The British Trust for Ornithology discovered that English nightingales concentrate in a drought-stricken area of Gambia, limiting their adaptability to changing environmental conditions.
Understanding the unique distribution pattern of British nightingales during winter offers crucial insights into their drastic decline in numbers, which has reached 90% since 1967.
