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
Rhinoceros Auklet, 37–41 cm, breeds colonially in burrows on North Pacific islands from California to Japan. Adults develop a prominent horn at bill base in breeding plumage plus white facial plumes. Nocturnal at colonies. Piscivore; dives up to 50 m for sand lance and herring. Winters at sea.
