About These Birds
Razorbill
Razorbill, 37–39 cm, is an Atlantic alcid with a deep, laterally compressed bill crossed by a white vertical bar. Breeds on Atlantic cliff colonies from Maine to Greenland and Iceland to Norway; winters at sea. Dives to over 100 m pursuing fish. Strongly monogamous; pairs reunite annually at colonies.
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.
