They scared the daylights out of me too, at first! Your birdy is going through sexual maturity. What she is expressing is a sexual behavior. You are now her mate. These little fits usualy happen when you pat or rub under the wings, on the back. Try not to do that, and these episodes should go away

But don't worry, your bird is fine. If felt so silly when I called the vet when I first saw it! LOL
