Funny how birds talk its not always what you think.My sulpher does sounds and my rosebreasted spits out a few words.She has to be very excited and its useally facing her food dish or preening herself. Ive heard males tend to talk more.[it seems true at my house] I think Penny And Mya have a Blue eyed and she talks.
Yes they can. I have heard one talk at the parrot farm i used to work. Not much, he said something like 'nice' (in dutch) But they can. It doesnt sound anything like an african grey can ......
