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.
Kittlitz's Murrelet
Kittlitz's Murrelet, 23–25 cm, is an enigmatic auk that nests on rocky tundra above the tree line in Alaska and eastern Russia, often near glaciers. Mottled brown in summer, white in winter. Critically dependent on glacial outwash for foraging; Vulnerable as glaciers recede. Piscivore.
