Hundreds of millions of birds die in the U.S. every year from collisions with large human-made structures, including buildings, communication towers, and wind turbines.
Breeding and the greening of the landscape are tied to another major spectacle of spring: the mass movements of animals as they take advantage of spring’s bounty. Meet the scientists who track the journeys of animals such as butterflies, birds, bison and bats over vast distances, from winter refuge to spring nesting grounds.
As another sneak peek into what we can expect during our three-day live broadcast, we connected with migrating bird expert, Peter Marra. Watch to learn more about the process of tracking the birds' migrations and Pete's work with the Smithsonian National Zoo and Conservation Biology Institute.
Check out swarm intelligence, essentially a living embodiment of social media in the natural world.
In this scene from EARTHFLIGHT: North America, a flock of brown pelicans fly over the Pacific in search of fish. Juvenile brown pelicans, born in the warm waters of Baja California, follow their elders north, as they soar above a pod of breaching humpback whales.
One of the greatest migration stories of the natural world, set against the backdrop of one of Africa’s most surreal landscapes. Great Zebra Exodus premieres Wednesday, May 15 at 8/7c on PBS.
The Drakensberg Mountains are Southern Africa's Alps, rising more than 11,000 feet into the sky. But beneath their beauty lies a hostile environment for the creatures that live there. Each spring, drenching rains destroy the grasslands at the base of the mountains, and those who would survive must climb up sheer cliffs, through storms and snow, to reach the carpets of new grass on the plateau.
This is the story of the fabric of life, and how all species are connected. At its center is the horseshoe crab, a creature that has remained virtually unchanged for eons. Its annual spawning produces millions of eggs that are the lifeline for a tiny bird, the red knot. But horseshoe crab numbers are plummeting, and the pyramid depending on this age-old creature is about to come crashing down.
