第2341期:Five new British seabird species at ris

Britain's miles of coastline are home to globally important seabird colonies, with more than 20 different species breeding on cliff tops or foraging out at sea. But many populations are in trouble, hit by multiple pressures from climate change to overfishing. 

在英国数千英里的海岸线上分布着许多在世界范围内都有着显著意义的海鸟群落，这里有超过 20 种海鸟在悬崖上筑巢繁衍或在海中觅食。但由于气候变化和过度捕捞等因素带来的生存压力，其中不少鸟类种群的生存都陷入了困境。 

In the latest health check of seabirds, conservation groups have added five more species to the red list of British birds facing the highest level of conservation concern. The new additions are the Arctic tern, the giant skua, the little-known Leach's storm petrel and two types of gull – the common gull and great black-backed gull. 

在最新的一项对海鸟的生态健康检查过后，动物保护团体将五种鸟类添加到了英国鸟类红色名单中。新添加的鸟类包括北极燕鸥、大贼鸥、较少为人所知的白腰叉尾海燕，以及两种鸥属鸟类——普通海鸥和大黑背鸥。
