Tokyo's Hidden Wildlife -- Tama River, Japan
A jungle within Tokyo? It may come as a surprise that many wild animals, including deer, boar and badgers live right near humans in the Tama River. Improved flood control and regular maintenance have resulted in a range of environments, such as grasslands, woods and exposed rocky and sandy bars extending several hundred meters in all directions. Motion-activated cameras set up along the riverside and animal trails revealed a host of surprises, including a weasel family's hidden fishing spot!
