The Bering Sea in winter, framed as it is by Alaska and Siberia, is frigid, stormy, and dark. But remarkably, some birds seem right at home there. The Crested Auklet is one such bird. And they have some unique qualities. Crested Auklets bark like Chihuahuas. Also, these seabirds exude an…

A winter morning in Oaxaca, Mexico—a great time to visit old friends who spent the summer in the United States. Yellow-rumped Warblers and Western Tanagers—northern summer-nesters that winter in western Mexico—mingle with resident Berylline Hummingbirds, Gray Silky-Flycatchers, and this…

Near the city of Crato in northeastern Brazil lives a critically endangered little bird — the Araripe Manakin. It’s a little larger than a sparrow, it’s beautiful, and it lives on the slopes of a very small area in the Araripe Plateau. And because the Araripe Manakin wasn’t discovered…

Like an expert angler, a tern can read the surface of the water to find where to catch its next fish. Scientists piloted a drone to track the flight paths of terns on the hunt. The terns sought out turbulent water. A vortex formed by colliding currents traps fish near the surface, where…

Around this time of year, Common Mergansers cross the US-Canadian border on their way to wintering grounds in the Lower 48. But how do they know when to go? Ducks are well insulated against frigid winter temperatures, but mergansers can find their fishy prey only by diving below the…

An owl's seeming ability to rotate its head in a complete circle is downright eerie. An owl's apparent head rotation is part illusion, part structural design. Because its eyes are fixed in their sockets, it must rotate its neck to look around. It can actually rotate its head about 270…

The landscape around Joanna Buehler’s home on Lake Sammamish was once completely barren. But today, it provides food, water, and refuge for many species of birds. You can create a bird sanctuary in your own yard by selecting native plants adapted for your area. If you’re lucky, nature will…
