I also have a cockatiel "Honey" she is almost 8 years old now. Females, generally speaking... don't always talk. I still repeat the same words every morning when I open her cage and during the day but nothin'...lol...However, she can communicate with me perfectly well without saying a word...She knows how to get what she wants, when she wants it....Spoiled rotten to the core...
Males on the other hand pick up talking easily, so they say. I'm very happy for you and Bird!!!!! Thats way COOL!!!!!
