Prairie dogs are America's answer to the meerkat - small, sociable and exceptionally cute. This offbeat film narrated Rob Brydon takes us to the Wild West where prairie dogs live in huge colonies known as 'towns'. Like meerkats, they are comical to watch, but there is a whole lot more to prairie dogs than just being cute - they can talk. 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's a bold claim but is he rightCon has devised a series of cunning field experiments to help prove his point. 美劇網（ www.jessietabla.com）<<BBC自然世界.語言大師草原犬鼠>>，別忘了推薦給你的好友！
