In September, a Pacific Golden-Plover wings its way toward the Hawaiian Islands, where it will spend the winter. Its wings span a full two feet. The plover fueled up for migration by plucking summer berries from its Alaskan tundra breeding grounds, storing fat for its 2500-mile flight…

This dusky forager among the mussels and barnacles goes by the curious name of Wandering Tattler. It was likely named for the notion that its rapid whistles alert other birds to the presence of a hunter, or other predator. And while it's not certain that the sandpiper actually "tattles,"…

We owe a lot to the nature recordists who travel the world to document the calls and songs of birds. Recordist Martyn Stewart describes how he obtained the call of a Rough-legged Hawk (like this one), which nests on the tree-less Arctic tundra: "I had seen this on the Arctic National…

Great Horned Owls stalk their prey from perches, while gliding on silent wings, even while walking on the ground. Their prey ranges in size from crickets to turkeys. They take skunks, marmots, muskrats, and house cats. Mink and jack rabbits are on the menu, as is the occasional porcupine…

If you want to see an albatross, you'll have to go offshore. Our goal lies west: the edge of the Continental Shelf, 35 nautical miles away. In the pelagic realm, we pass among thousands of shearwaters, migrating south to nest near New Zealand, in the austral summer. Someone shouts…

When you encounter a flock of wild guineafowl anywhere from Senegal to South Africa, they will usually be running, squawking as they go, obviously panic-stricken about something. Guineafowl are funny-looking birds, and their actions and calls are even funnier. These are calls of alarm…

Within two weeks of hatching, a young male Bewick's Wren is already out of the nest, skulking in the shrubbery. Over the next couple of weeks, the fledgling will learn at least 15 different song variations his father sings. After he wanders off to find his own territory, about a mile from…

Archaeological discoveries in Chile strongly suggest that chickens reached the New World about 100 years before the first Europeans. They apparently crossed the Pacific aboard outriggers piloted by Polynesian navigators. The DNA found in chicken bones in Chile resembles that of bones found…

After sunset, the American Robin sings faster and more elaborate versions of his daytime songs. Some birds have more than 100 songs! They time their singing to the intensity of light as well as to the time of sunset. When dark clouds roll in, they get rolling earlier. Males sing mainly to…

A waterfall roars in a box canyon deep in the Cascade Mountains. Just after sunset on a July evening, a slender, dark shape—a Black Swift—arcs into view, just in front of the waterfall. The swift builds its nest in crevices behind waterfalls in the western mountains, from British Columbia…
