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.
Japanese Murrelet
Japanese Murrelet, 26–28 cm, is a Vulnerable alcid endemic to Japan, breeding on rocky islets in the Pacific. Black head with a small white supercilium stripe; grey back. Nests in rock crevices; chicks led to sea while still tiny. Piscivore; threatened by gill-net bycatch and feral predators on islands.
