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.
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
