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.
Marbled Murrelet
Marbled Murrelet, 24–25 cm, nests on the mossy branches of old-growth forest in western North America — one of the few seabirds to nest miles inland without excavating a burrow. Threatened; dependent on old-growth Douglas-fir and redwood. Piscivore; dives for sand lance near shore. Endangered.
