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.
Thick-billed Murre
Thick-billed Murre (Brünnich's Guillemot), 39–43 cm, breeds in enormous cliff colonies across the Arctic from Newfoundland to Siberia. Thicker, shorter bill with white gape line. Dives to 200+ m — deepest diver among alcids. Piscivore; takes capelin, cod. Vulnerable to climate change in the High Arctic.
