Cypress trees draped with Spanish moss rise from still, dark water. A Barred Owl hoots mightily as an alligator slithers by. It's morning on the bayou. Bayous are found in much of the Southeast from Arkansas to Alabama, across flat land that drains into the Mississippi River. A bayou's…

The tiniest bird in mainland North America: the Calliope Hummingbird - a 3-1/4-inch jewel, weighing in at just a tenth of an ounce. These birds migrate north each spring from Western Mexico. From its perch, a male Calliope Hummingbird surveys its territory. This exquisite bird was named…

In a Western ponderosa pine savanna, tall pines dot an open, grassy landscape. A Western Bluebird flits from a gnarly branch, as this Cassin's Finch belts out a rapid song. The trees here grow singly or in small stands. Upslope, the pines become denser, mixing with firs. Downhill, the…

If this week's bright full moon pulls you outside, pause for a moment and listen. You might hear migrating songbirds overhead. Most songbirds migrate at night, when fewer predators are out. The migrants stop, feed, and rest during the day. However, many scientists believe that the main…

One of the world champions of long-distance migration is the Arctic Tern. Arctic Terns nest across the far northern reaches of the continent during our summer, then fly south to Antarctica for the rest of the year. Some will circle the polar ice-pack before heading north again, completing…

Emily Dickinson: "The Birds begun at Four o'clock..." As the first rays of sunlight fill the trees on a spring morning, a symphony of birdsong erupts. As early morning light extinguishes the stars, male birds begin to belt out their songs. One of the magical gifts of spring is the dawn…
