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.
Scripps's Murrelet
Scripps's Murrelet, 22–24 cm, breeds in crevices on Channel Islands off southern California. White underparts contrasting with dark grey upperparts; white split extends up flanks. Nocturnal at colonies. Chicks lead-march to sea within 2 days of hatching. Piscivore; threatened by light pollution and introduced predators.
