Description: To understand the conversations among the carrier pigeons, let's first go back to basics and check out the books of some of the city's most prominent ornithologists. Do you find any descriptions that might be useful?
Completed: I knew it, Keira, you are a brilliant researcher! If only we had a manual on the principles of bird communication, we'd be one step closer to decoding pigeon conversations. Now it's just a matter of technology!
