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.
Long-billed Murrelet
Long-billed Murrelet, 26–28 cm, breeds remarkably far inland in old-growth forests of Siberia, nesting directly on mossy tree branches — no burrow. Sea-going for the rest of the year, wintering off eastern Asian coasts. Piscivore; dives for small fish. Near Threatened; nesting ecology unusual for alcids.
