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.
Guadalupe Murrelet
Guadalupe Murrelet, 22–24 cm, breeds only on Guadalupe Island off Baja California. Very similar to Scripps's Murrelet but with more extensive white on the face. Critically Endangered; fewer than 1,000 individuals; nesting habitat threatened by feral cats and goats (now being controlled). Piscivore.
