<p>　　Prairie dogs are America&#39;s answer to the meerkat - small, sociable and exceptionally cute. This offbeat film narrated by Rob Brydon takes us to the Wild West where prairie dogs live in huge colonies known as &#39;towns&#39;. Like meerkats, they are comical to watch, but there is a whole lot more to prairie dogs than just being cute - they can talk.<br/>　　For 30 years Professor Con Slobodchikoff has been recording their calls in response to predators like coyotes, hawks and badgers. He believes he has discovered a language second only to humans in its complexity. It&#39;s a bold claim but is he right? Con has devised a series of cunning field experiments to help prove his point.</p>
