Mango my red belly is too quiet. He talks a bit when we cuddle him, he makes kissing sounds and gives smooches but he is otherwise silent. If we put him on his cage and leave the room he peeps at us. It gets louder and louder the longer we are gone but he never screeches. He does yell at broccoli, but its not loud. I have heard some serious screams and was expecting a LOT more noise when we got him. That said, if we are home he is pretty much always with us unless we are doing something that we dont think is safe for him.
