Now, I do NOT understand a single word of what the man or the bird are saying but just listen to the man's voice... low, soft and calm and in soothing cadence. And listen to the bird answering (using the same calm and soft voice of the man) and him repeating what the bird said and you can tell the bird is talking very clearly and giving the right answer to the question. Plus, you can see the bird is super relaxed even though it is, obviously, a training session -she (couldn't quite see the profile clearly but it looks like a female) even stops to give the man a kiss which the man retributes without blinking an eye. Like I said: don't know what the heck they are saying but I loved it!
