My parrot will on every occasion that it stumbles, let out a surprised "Oh!" followed by a "Good boy!" when he gets back up again. I didn't sit around all day teaching him to say "Oh!" whenever I pushed him off the branch and praise him when he got back up again. I also don't tell myself I'm a "Good boy!" whenever I get back up from a stumble (which thankfully doesn't happen often at home to begin with). I'm sure my parrot doesn't know what "Oh!" or "Good boy" means, that is what the words mean in a human context. I'm also sure that he doesn't know what snapping finger noise followed by a stern "Ah-ah!" means, but he has used that on one occasion when he was mad at me and wanted to tell me to back off if I treasured the skin on my hands. (A learned behaviour from his first and previous owner). ...but at the end of the day, speech is in many ways "just" a series of correct sounds at correct times in correct situations, right? Does my parrot have a conversation with me? Well yes, sometimes, but not with words. Does my parrot mimic human words and phrases? Also yes, and sometimes in the most perfect situations possible.
