Elephant language studies video

There was a great bit on CBS "60 Minutes" last night about people studying elephant language and behavior, trying to put together an "elephant dictionary." They've posted the entire 14 minute segment online, along with a couple of shorter videos. If pachyderms interest you, take a look!
