Season 18, Episode 14 Earth Navigators

First Aired: April 23, 2000

“Everywhere,” says narrator Peter Strauss, “animals large and small are on the move.” This hour follows the migrations of four peripatetic species. First up: Monarch butterflies, which travel northward from Mexico each spring---a journey that takes three generations to complete. On East Africa's Serengeti Plain, wildebeests, a million strong, are constantly searching for water and land for grazing. Whooping cranes are seen en route from Europe to Iceland (where they're joined by Arctic terns, which migrate from pole to pole). And sockeye salmon must swim from Alaska to their “home rivers” farther south. It is literally a “life's journey.”
