The Atlantic Coast, where wild horses battle, bald eagles chase ospreys and sharks protect fish; raccoons navigate city life, black bears search for food in ancient forests and a 130-year-old oak tree prepares for winter's arrival.

The Wild West, where coyotes face a snowbound Yellowstone, rattlesnakes emerge in the hundreds, woodpeckers compete to store food, bison battle on the Great Plains and cranes gather in vast numbers on their age-old migration.
