I am scrambling around in my dusty memories trying to remember who...anyway, someone in this forum sent me the DVD of that documentary, Pat.
I don't know how much of it was solid science and how much is anthropomorphism, but I would not be shocked to know that such a vocal and intelligent bird as a wild turkey would have a variety of vocal calls that could be modified and strung together to express limited concepts. I mean we have proof already, we've determined that certain calls are for breeding, some are alarms, some are just general conversation amongst the flock as they are feeding. Researchers now have determined prairie dogs have different warnings for ground predators versus aerial predators in order to give the correct warning to the dogtown.
