About These Birds
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
Common Murre
崖海鸦（约1公斤）是一种大型海雀，翼展约70厘米，在悬崖峭壁上密集繁殖，不筑巢，直接将卵产在岩脊上——卵形为梨形，滚动时呈圆弧形，不易滚落。以鱼类为食。无危；种群数量庞大，但在某些地区面临延绳钓混获和油污的威胁。
