近期，又有五种海鸟被列入了英国鸟类红色名单。该名单记录了被认为在英国境内亟待保护的鸟类，比如海鹦鹉。

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.
