The raucous laughter of the Common Murre rings out from a nesting colony, high on a narrow ledge on a sea cliff. Precarious as their nest site is, Common Murres nest by the thousands along the Pacific Coast, perhaps millions north along the Bering Sea. Their eggs are pointed at one end and blunt at the other, so they spin on the ledge rather than tumbling into the sea. Common Murres stand nearly a foot and a half tall. With legs set far back on their bodies, they look much like the northwestern equivalent of penguins of the Southern Hemisphere. Learn more at BirdNote.org.
