We had a visitor over Thanksgiving -- Miss Duke, an African grey parrot, kind of like Trouble but a little bigger. She's quite the talker. And not only that, she rings like a telephone and beeps like an answering machine and then makes noises like a telephone conversation. My person thought it was very interesting and paid a lot of attention to Miss Duke and laughed and laughed when she talked. Hmmmmph! Well, I can beep like a microwave oven or a telephone, too! And I can say "Pretty bird" all day long if I want to. But my feeling is that just about anything else I might want to say is easily conveyed with a few loud squawks, so what's the point of using all those other words?
