I'd heard about this one before, but it's great to see some research done on it. If you think about it, humans communicating with birds is not all that astounding - interspecies communication abounds in nature. Nonetheless, it does make for a fascinating case study. What I found most amazing was that the Yao have developed a sort of "bird call" specifically for this use, and that the birds actually understand the exact meaning of this call! Perhaps birds aren't as stupid as we often think after all...
