Wild Chronicles goes behind the scenes of the new 3-D National Geographic Giant Screen Film "Sea Monsters: A Prehistoric Adventure." Painstaking scientific research, computer generated imagery and cutting-edge cinematography brings the powerful marine reptile predators from the dinosaur age to life as never seen before. Adventure and Exploration: A team of photographers from National Geographic travel to Mexico's 300-acre Triunfo Reserve to conduct a rapid assessment visual expedition, or RAVE for short. The Triunfo, a cloud forest enshrouded in a wisp of fog, may be one of the last strongholds of the legendary quetzal. The photographers are hoping to raise awareness about the ecological habitat as conservationists worry that a proposed road could cut the habitat into fragments. GeoCast: Held illegally as an exotic pet and later rescued, a young male African lion attempts to establish his own territory at Colorado's Wild Animal Sanctuary. Created 25 years ago, the sanctuary in the Rocky Mountains provides large carnivores room to roam in a home away from home. Across the globe, many countries are tracking a fowl problem - avian flu. For some people who depend on raising poultry for food and money, the birds that sustain them could end up sickening them. In a program sponsored by UNICEF, health workers are going door to door to teach people how to protect themselves from the bird-borne virus. Photographer and National Geographic Grantee James Balog, facing his greatest challenge yet, is determined to catch global warming in the act. Anchoring 26 time-lapse camera setups next to 16 glaciers around the world, Balog hopes to capture glacial retreat in a time-lapse documentary film made from over 300,000 individual photographs recorded over a two year period. Dolphins astound with their strength, grace, flair and intelligence. There are more than 30 different species of dolphin around the world and there is much we do not know about them. Wild Chronicles wades into the surf to investigate their behaviors.
