This is BirdNote.
The miracle of flight, that enviable ability is what birds are best known for. Yet among the nearly 10,000 bird species worldwide, only a few dozen can fly under water. The Common Murre is among them.
We most often think of the penguins of southern latitudes as underwater fliers par excellence. In the Northern Hemisphere, it鈥檚 the family of seabirds called alcids or auks that wing their way under the marine surface. Puffins, murrelets, guillemots, and Common Murres are all underwater fliers.
When flying above the water, the eighteen-inch-long Common Murres must flap frantically to stay aloft. But beneath the waves, using their flipper-like wings, they are streamlined, masterful swimmers, black-and-white torpedoes chasing fish even at depths of several hundred feet. To reduce drag, the murre holds its wings only partly extended, flying through the submarine world with powerful strokes.
Several hundred feet under the water鈥攊t's amazing, it's it?
