Ingeborg

Our family is pretty fresh with our parrot, even though we've both had birds earlier in our life. We have had our AG, named Ingeborg, since late april, and I guess we are still learning to know her - her likes, dislikes moods and sometimes naughty behaviour. I am the man in the family and Ingeborg has definitely connected strongest to me - I'm more or less able to do whatever I want with her. She is very trusting, and has no problems letting me touch her more or less all the time. I know about her "leave me alone" bites (however, she actually rarly bites me just moves away or crunches down so I can't get to her feet (when she's tired and doesn't want to take the effort to move into the cage ). I know about her "stop messing inside my cage" bites, and also her "I'm getting pretty darned annoyed with this toy, and everyone who has ever been in contact with it" bites. And not to forget - "I didn't like that you tried to teach me that" bites that happens when she's sitting quietly on my hand after doing some kind of unwanted training exercise. It's like - here, have this after trying to make me go close to the sink to take a bath. Most of the time I just let her bite me without moving my hand away, trying to talk softly to her at the same time - she rarly bites hard enough for it to hurt, even though I know that she's more than able to. What I'm wondering about is her kind of soft and careful biting when I'm cuddling with her (she is very cuddly in the afternoon and evening). She is twitching and turning her head (180 degrees and more) to try and slowly nip at my fingers when I'm scratching her neck. There are no signs of her not liking it, or attempts to get away - quite the contrary. She doesn't really bite in a way that hurts, but just squeezes her beak around my finger. However, if I let her continue she will bite a little harder, as if she gets a little too excited. My assunption is that she's actually just doing this to play, but I haven't seen anyone mentioning this when discussing african greys and biting. Does anyone have any experience with this, or anything to indicate whether I'm right or wrong?
