Wild Chronicles

Journey Of Discovery

Season 4, Episode 7 of 12

News from Nature - Like their mythical namesakes, vampire bats feast on fresh blood in order to survive. Seeking out warm-blooded domestic livestock for a meal, the tiny bats thrive in the tropical regions of Central and South America. However in Peru, vampire bats are increasingly targeting humans and the encounters are turning deadly. National Geographic grantee Daniel Streicker investigates the cause. Stories from the Wild - Every fall pronghorn antelope trek from Grand Teton National Park to their winter habitat in the Upper Green River Valley of Wyoming. The one hundred mile migration is one of the longest in North America. But human development is fragmenting the pronghorn's habitat and conservationists, including National Geographic Young Explorer grantee Joe Riis, worry the ancient migration route could be severed and lost forever. Field Reports - In Tasmania, Wild Chronicles host Boyd Matson leads the National Geographic Kids Hands-On Explorer Challenge Expedition Team on a conservation project to save the endangered Tasmanian devil. Tasmanian devil populations have been decimated in the last decade by an untreatable facial tumor disease. Researchers hope that raising disease-free insurance-populations in captivity will save the devilish marsupial. Adventure and Exploration - Over the past 10 years, Arctic ice has been melting at a rate unparalleled in recorded history. Battling sub-zero temperatures and hungry polar bears, a team of polar explorers attempt to traverse 1,400 miles across Canada's Ellesmere Island to discover the melting ice's impact.
