a Question about my Cockatoo

hey all
i really enjoy this great Forum as I DO thank all those who working on it.
let me tell you about what I'm looking for but before I need to tell you in brief about my Cockatoo . I have a triton Cockatoo
as I got it the man told me he is between 3 to 4 years. Now it's one month since I have it and everything goes fine with me except one thing, which is talking !! she just mumbling and that thing when she usually do before got sleep with her beak.
she always stays with me as now I have nothing to do so most of the time she with me and in the same room in her Big cage opened door playing dancing all good things, also she has a good health.
i talk adorably with her also with lovely tone i actually treat her just like a princess .
but the problem is in talking never heard any thing from her only mumbling and sometimes strange voices !! I'm afraid she never talks as I knew she talks less words but at least she must says a word or a few maybe.
please help me what can I do !!

Some birds never talk.

Thats just the way it is :3...

Just love her as she is? And be patient maybe one day she'll surprise you!

All you can do is keep talking to her, repeat words, always say certain words/phrases for certain things- like "good morning!" when you greet her in the morning, or "hello!" when you come into the room. It takes time, but even if a bird has the ability to talk, doesn't mean they will.

thanks all
I always talk to her staring with simple words like hello, bye, baba, mama and when i serve food to her I say food. but I guess it's matter of time and the one who sale it for me told me she talks with many words but don't know why with me not !!

As said above some birds just don't talk, love your bird the way she is

Watch her eyes for pinning(the pupil getting small and big rapidly) in response to certain words, use those words more often.

thank you very much , i actually i love it very much and my family too.
I was thinking to sale it and get another one but really she's adorable one
thanks all for helping me

When you have her out, repeat words and touch her beak at the same time. Make the words exciting and repeat them in different joyous/exciting tones.
They are also easily trained for habits, as others have said, always greet her and leave her with the same words and she'll start associating the action with the words.. Use the words in context and she should pick some things up.

She may also not be a talker, either way, she's beautiful and will make a great companion!!
I love Butchie's "too talk" when he mumbles and sounds like a demon.. It's pretty funny, especially first thing in the morning he's like a grumpy old man!!

Some birds are called "closet talkers" because their owners only hear them talk when the bird is in a different room than the human. It would be a contact call, trying to make sure the human is nearby. The fact you are always in the same room as your bird means she does not have to call to you, so less talking is needed . . .

It sounds to me like her character is charming. I once knew a VERY talkative amazon who was aggressive, both inside his cage & out. No bird is perfect - you need to decide whether a charming bird who might eventually talk is a better fit for your family than a talkative one who might hate you or be cage aggressive, or whatever.

To me, one that is an amusing companion who likes all its human flockmates is way better than one who talks up a storm but doesn't like its flock. But that's just me.

I agree with KB, character is a lot more important than talking ability. You say you cocky talked in the petshop, it's possible she hasn't gotten used to your voice, and human voice characteristics vary a lot, especially male/female- my wife always gets better responses from our birds, apart from the corella, than me. The corella says almost nothing I can understand though! Just give it time, Fahad, and enjoy your cocky as she is, have patience and she may surprise you with whole sentences!

Definitely, patience and persistence. The more she bonds with you, the better! Some birds never speak clearly, and some are chatterboxes. Any speech at all is amazing considering their anatomy is so so different than ours. But the more repetition, the better if there are certain words you want her to say! Don;t give up - cockatoos can live a very long time, so you are just at the beginning of this relationship!

Think how long it takes human children to talk in intelligible words!

When Cockatoos talk they mumble half the time or say it so low you really have to listen to what they're saying. I never purchase a bird solely on talking ability. That would be a wrong reason to own a bird. When you try to teach them talk, use single words and speak clearly then repeat. Like what others have mentioned already, your may never speak. You just never know.
