I was struck today by a quip I heard on NPR promoting an upcoming program with science writer Tim Friend. Friend writes for USA Today and has a book out entitled Animal Talk. I haven't read it (yet) but based on the tease I heard today I will.
The big picture of animal talk in the wild--of every species-- what they spend so much time chattering to each other about is sex, real estate, who's boss and what's for dinner.
Listen if you can.
