Animals, like humans, need a place they can call home to provide a safe and stable place to raise a family, but they go about building it in entirely different ways. Whether it is a bird’s nest, bear den, beaver lodge or spider web, these are homes of great complexity, constructed from a wide range of natural as well as man-made materials. This three-part series investigates just how animals build their remarkable homes around the globe and the intriguing behaviors and social interactions that take place in and around them. Hosting the series is ecologist Chris Morgan (Siberian Tiger Quest, Bears of the Last Frontier), who serves as guide and real estate agent. He evaluates and deconstructs animal abodes, their materials, location, neighborhood and aesthetics.
