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.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
