Yeah she can talk, laugh, wave. Shes very intelligent you can actually hold a pretty good conversation with her. I don't mean she just says random things she understands and responds appropriately.
For example this happen about a week ago.
Me: *Sitting on the couch*
Bird: *Climbs up my leg* What are you doing?
Me: Just watching TV
Bird: Do you want an apple?
Me: No thanks
Bird: Why Not?
Me: I'm not hungry
Bird: Can I have an apple?
Me: Do you want an apple?
Bird: Please!
Me: Ok lets go get you an apple
Bird: *eating apple* yum yum yum hahaha
Me: is it good?
Bird: Yes!
Bird: *Finishes apple* Bye
Me: Where are you going?
Bird: night night *climbs in her cage shuts her door and goes to bed*
It's hard to believe the amount of intelligence she has. She is still learning new stuff all the time. Most people think they just repeat what they hear and they do but they also learn the meaning of the things they hear. They can learn the actions involved in them to. Like when she laughs the throws her head back and when she says bye she often waves.
