If he responds to his name, then I wouldn't change it Doing so would only confuse him at a time when he is already undergoing major changes.
What you might do is add to his name, so that he gradually gets used to the addition without losing the security of his originalname.

His wings may be clipped, so be careful. If he can't fly now, he might be able to in a few months. Moreover, even with clipped wings, some nandays are still able to fly to a limited extent.

I've heard of other species doing this, but never nandays. However, maybe if he's been around other birds, he's picked up this behavior.

Yes, give him a week or so to adjust -- longer if he still seems nervous. Instead, feed him and talk to him and sit by him to help him start to like you.
