Mireya Mayor

America's Greatest Animals takes us across North America on a revelatory mission: which of the continent's landmark creatures deserve to make the list?

In 2007, scientists from the Wildlife Conservation Society discovered there were an estimated 125,000 western lowland gorillas living in the remote forests of northern Congo. This find offers another chance to protect this endangered great ape and a first look at some unprecedented behaviour – including a knack for using tools. Now primatologist and National Geographic explorer Mireya Mayor ventures into the heart of the jungle to explore the great apes’ secret world. She gets a rare and intimate look into the family life of one gorilla group and witnesses individuals performing feats unexpected in the wild. Spectacularly photographed and featuring new scientific insight, Mystery Gorilla presents startlingly familiar animals like you’ve never seen them before.

Shock Docs: This is Halloween combines an impressive set of experts/historians and stars from many of the Travel Channel’s most popular series such as Ghost Nation, Destination Fear, Ghost Brothers, Kindred Spirits, Expedition Bigfoot, and The Holzer Files to reminisce on not only the history/origins of the holiday, but also recall their favorite memories of the celebrations, costumes, and scares.
