Phyllis,
I've delayed a response as your circumstances is different to mine, my adopted female Pebbles, came to me very scared, and she would freak out if approached. I just wanted to agree that things can take a long time, Pebbles certainly took a long time to build trust.
I also wanted to share one thing I have been trying with Gizmo (my male eclectus), again different circumstances, but perhaps a technique you could use, especially if your girl loves food like Pebbles does.
He has a nasty habit of biting if you try to touch him. I really should have worked with him on this problem early on, but I went with the idea that if he doesn't like it, then fair enough. My opinion changed a few months back, when he got caught in my wife's hair, and as I tried to help him untangle his foot, he grabbed my finger near the nail and took some skin (that really hurt....lol).
So I have been giving him treats (something that takes time to eat), and then while he is eating I will touch his foot, chest, wing, back of the neck, etc. It has taken some time, but I can now do this without food, well as long as I don't hang around too long

, and with food he will let me touch him pretty much without resistance (although I am yet to try opening a wing, I want to move on gradually).
Now I realise your circumstance is a lot different, but the idea is a bit reverse to the norm (treat after desired behaviour). It's more about gradually switching off the standard reaction response. With Gizmo the success wasn't really about being able to touch him when he had a treat in his mouth (I could do that on day one), it was about changing the standard reaction of being touched without a treat in his mouth from being bite said finger.
Anyway, perhaps that might be of some use in the toolbox of training.
Best of luck and keep us updated.
Cheers,
Cameron
