Scientific American Frontiers Season 13 Episode 8 Calls of the Wild

The episode of Scientific American Frontiers season 13 episode 8, entitled "Calls of the Wild," examines the communication abilities of various animals from around the world. Hosted by Alan Alda, the show takes viewers on a journey to explore the diverse range of animal vocalizations, including those of wolves, gibbons, and even prairie dogs.

The episode begins with Alda visiting a wolf sanctuary in Montana, where he observes the wolves' howls and their ability to communicate with one another across vast distances. Experts explain that there are several types of wolf howls, including the long-range howl used to locate pack members and the mournful howl used to signal distress.

Moving on to tropical rainforests, Alda encounters gibbons, a species of ape known for their unique hooting calls. Experts reveal that gibbons use their vocalizations to communicate with each other, with different calls holding different meanings. For example, a short, sharp hoot indicates danger, while a longer call signifies a request for food or attention.

In Arizona, Alda observes prairie dogs and their complex communication system consisting of barks and whistles. Experts explain that prairie dogs are able to convey information such as the type of predator and its location through their calls. The show also explores how prairie dogs create "towns" with intricate underground tunnels and chambers that serve as homes and escape routes.

Moving to the ocean, the show examines the communication abilities of humpback whales. Viewers witness the majestic animals' haunting songs and learn how these complex vocalizations are used to attract mates and potentially ward off rivals. Experts explain that humpback whale songs can last for hours and can be heard over vast stretches of ocean.

The episode also delves into the world of bird calls, exploring how many species are able to mimic other animals and even human speech. Alda visits a lab where researchers are studying the calls of parrots, which have been known to mimic human words and phrases. The show examines the cognitive abilities of parrots and other birds, revealing that they are capable of complex problem-solving and even recognize themselves in mirrors.

Throughout the episode, the show highlights the importance of these communication abilities in the animal kingdom. From alerting others to potential danger to finding mates and establishing territories, vocalizations play a crucial role in the survival of many species. The show also touches on the ways in which human noise pollution and habitat destruction can impact these communication systems, highlighting the need for conservation efforts to protect the diverse range of animal voices in our world.
