Listen to the earth awaken, as dawn circles the globe. Acoustic ecologist Gordon Hempton recorded these sounds around the globe. He's with SoundTracker.

Coast to coast, border to border, forest to feeder, the Downy Woodpecker goes about its business in 49 states. The smallest woodpecker in the United States, it turns up everywhere there are a few trees, except in the dry deserts of the Southwest and in Hawaii. Learn more at BirdNote.org.

Brown Pelicans are a regular sight today along the Gulf of Mexico and our southern coastlines. But these birds have not always been so plentiful. They were hunted for their feathers and as pests by fishermen. The Migratory Bird Act of 1918 protected their recovery. But by 1970, pesticides were killing pelicans outright and thinning their eggshells. The 1972 Endangered Species Act has helped lead to a gradual comeback. Learn more at BirdNote.org.

It's morning on the island of New Guinea, and the lowland forests erupt with the crowing calls of Birds of Paradise. Male Raggiana Birds of Paradise perform elaborate displays to attract females, sometimes even hanging upside-down with their wings pointing upward. Forty-three species of Birds of Paradise are found on or near New Guinea. Learn more at BirdNote.org.

When buying seed for your feeders, it’s tempting to get the biggest, cheapest bag. But not all bird seed is the same. Figure out the nutritional value of the seeds and whether your local birds can actually eat them. Black-oil sunflower seeds provide good protein and fat. Other good seeds include white millet and nyjer thistle. Avoid red milo, a livestock grain. And clean your feeding station regularly to prevent the spread of disease. Learn more at BirdNote.org.

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 move south, joining year-round residents. Learn more at BirdNote.org.

Most birds have the capacity to make red feathers, even those that lack red plumage. This discovery was revealed by scientists who studied Red-factor Canaries — a “hybrid” bird that is part canary, part Red Siskin, like this one. Both species have the “redness gene.” But Red-factor Canaries have a thousand times more red pigment in their skin. And why? Red-factor Canaries inherited the siskin’s “genetic switch” that turns on the redness gene in their skin. So just having the gene is not enough: if the genetic switch in the skin is turned off . . . no red feathers. Learn more at BirdNote.org.

By late January, some resident birds, such as the Northern Mockingbird, are beginning their spring singing. When you step outside on a particularly sunny day this winter, a Fox Sparrow like the one pictured here may be warming up for the coming spring. And as far north as British Columbia, Pacific Wrens are singing in earnest by mid-February. So the singing season never entirely stops. Learn more at BirdNote.org.

The flocking movements of homing pigeons are governed by a pecking order. Higher-ranked birds have more influence over how the flock moves. Leading birds change directions first, and followers swiftly copy the leader's movements. And birds at the front of the flock tend to make the navigational decisions. In other words, the pigeons follow the leader. Or leaders. learn more at BirdNote.org.

The goose of today’s farmyards was domesticated about 3,000 years ago from the Graylag Goose, the wild species found today throughout much of Europe and Asia. To ancient Egyptians, the goose symbolized the sun god Ra. Greeks linked the goose with Aphrodite, the goddess of love. And geese are prominently featured in the Shijing, the oldest existing collection of Chinese poetry. Learn more at BirdNote.org.
