I-5 between Sacramento and Redding parallels one North America’s great wildlife migration routes. Known as the Pacific Flyway, it runs the length of the Central Valley, where the birds find plenty of food and water. Once composed of oak woodlands, grasslands and marshes, this area now grows rice, nuts, fruits, and vegetables.
