American Spring Live: Migration
NATURE, television’s longest-running weekly natural history series, has won more than 200 honors from the television industry, parent groups, the international wildlife film community and environmental organizations, including the only award ever given to a television program by the Sierra Club.
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 they attempt to uncover the precise triggers and timing of migration and its impact on other animal species, the scientists grapple with how these patterns and behaviors may shift due to climate change.
