Does the image of a frozen birdbath bring to mind a small yellow bird with ice skates? Birds need water in all seasons, for drinking and for bathing. When the water is frozen, you can thaw it with hot water. Or go the slightly more expensive route and add a heater.

The Golden-crowned Kinglet weighs six grams, about the same as two pennies, yet winters as far north as Alaska and Nova Scotia. The birds move through the forest in small flocks and feed constantly, taking in enough tiny caterpillars to maintain their internal furnace at 110°F. And their…

As Bobolinks return to North America from the tropics each spring, they have good reason to sing with joy. The two-ounce birds have completed one of the longest migrations of any songbird: roughly 6,000 miles.

Early this fall, the tiny Wilson's Warbler began its long migration to Belize, where it winters. Navigating by the stars, the 1/4-ounce bird made a series of night flights spanning more than 2500 miles. This warbler returns to the same coffee plantation each year. Taller trees that shade…

When it's just too hard to see the bird you hear, let your ears take over! Listen for the qualities of the sound as well as the pattern. A flute-like and upward-spiraling sound is characteristic of this Swainson's Thrush. Quite a contrast to the plaintively whistled notes of a Black-capped…

Driving the freeway or a narrow country road, you may glance up at a light pole where a large hawk sits in plain view. If it's brown and somewhat mottled, and its small head and short tail make it appear football-shaped, it's probably a Red-tailed Hawk. During winter, many Red-tailed Hawks…

The Greater Honeyguide's demanding call is not aimed at a member of its own species. Instead, the bird guides people in search of honey through the forest, directly to bee hives. The bird flies to a colony of bees living in a hollow tree. The human follower exposes the hive with an ax and…

In a tropical woodland in eastern Australia, you glimpse a Southern Cassowary, a huge flightless bird that must rate as the most prehistoric looking of all birds. Cassowaries are capable of making remarkable sounds, including the lowest known bird call in the world, barely audible to the…

Ever wonder how the avian idiom, “A little bird told me,” came about? The consensus is that the saying springs from the Old Testament of the Bible -- a maxim from Ecclesiastes. By the mid-16th century, the “little bird” showed up in collections of proverbs. In 1711, the satirist Jonathan…

The boreal forest is a vast band of spruce and poplar, extending from coast to coast across Alaska and Canada. Called North America's "songbird bread-basket," for a brief time, it teems with song. Birdsongs heard on this show include a Common Loon (like this one), Swainson's Thrush, White…
