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.
Rhinoceros Auklet
角嘴海雀 (Cerorhinca monocerata)，体长约37厘米。繁殖期嘴基部具角状突起，嘴橙色，有白色须状饰羽；冬季突起消失，嘴色变淡。体羽上体黑色，下体白色。分布于北太平洋。以鱼类潜水捕食，在崖缝中营巢。
