Nature's Architects August 13, 2011

Explore bee hives, watch parakeets turn a telephone pole into an apartment complex, and find out how many termites it takes to build a skyscraper. Building beautiful and complex structures is not a uniquely human trait, but without blueprints, how do other animals do it? In 'Nature's Architects,' investigate the creative, industrious and skillful craftsmanship of other animal builders, around the world and in our own urban environment.
