further to my reply, Clarence knows the dogs by their "specific" bark, and responds to each...i.e. Gizmo (Jack Russell) barks, Clarence sez "Gizmo, shut up", Tucker (the other Jack Russell) barks, Clarence responds "Tucker go outside", or "Tucker - get your toy". Of course this initially was a conditioned response/mimic...however after a year, the bird truly knows which dog is barking and replys with an appropriate response, unprompted....these Greys are truly amazing. Now he's on to a Gatorade kick, and when thirsty, asks for Gatorade. We've avoided most "cuss words", however when dropping a toy or his food in the cage or on a perch, his unprompted response is "oh shit, what a mess".....
