About These Birds
Little Auk
Little Auk (Dovekie), 17–19 cm, is abundant in the High Arctic, with hundreds of millions breeding in Greenland and Svalbard — one of the world's most numerous seabirds. Tiny, black and white, stubby-billed. Planktivore; dives for copepods. Winters at sea in the North Atlantic, often far offshore.
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.
