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.
