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.
Common Murre
Common Murre, 38–46 cm, is among the most abundant seabirds in the North Atlantic and Pacific. Breeds on cliff ledges in huge colonies; single pear-shaped egg rolls in a circle rather than off the ledge. Piscivore; dives to 180 m for fish. Flies with rapid wingbeats; waddling gait on land.
