Welcome to another day in the strange, beautiful, and increasingly imperiled world of the rain forest - the most alive place on Earth. Here in nature's living laboratory dwell over half of all living things, from delicate ochids that grow in air and butterflies as large as your outstretched hand to three-toed sloths that dangle motionless from trees and countless plants, insects, and birds that don't even have name yet.
In the moments before the violet of a tropical sunrise give way to graphite and then cobalt, the quiet of a velvety night is pierced by the ringing call of a bellbird. Louder than any barnyard rooster, the bird's revelry touches off a sunrise serenade of buzzing insects, croaking frogs, and howling monkeys.
Dans les airs, dans l'eau et sur les continents, des espèces fascinantes sont en marche. Leurs voyages en quête de nourriture, d'un temps plus clément et d'un endroit sûr où faire naître leurs petits sont appelés migrations. Et la manière dont ces animaux trouvent leur chemin est stupéfiante.
