Agreed.Our three tiels have very different levels of desired human interaction. Igor comes over for scritches when he wants them, then leaves when he's had enough. Sunshine will fly over to anyone with a free hand for scritches, and will remain with that person all day, if you let him.Let her hang out near you without trying to touch her. Many cockatiels never like to be pet, but maybe she will after months or years of being together and developing trust, you never know. You can still have a very strong bond without cuddling.
You mean like the game, "Let's pretend I want scritches, but I really just want to attack your finger?"Callisto likes to come over to me but when I pick her up she complains. I think that's related to her bad foot. Kuiper will come over to me, too, but when I try to pet him he either runs away or tries to bite me. I've had a few cockatiels, though, who always liked to come over to me and be handled and petted. Just depends on the individual bird.
She might not want to be petted or maybe she is just playing a game with you.
