I am sure by now you have found out that your Grey is simply "in love" with you. As I was reading your post my African Grey was regurgitating peanuts on my lap.LOL-YUM! He kind of hunkers down and spreads his wings a little bit and breaths heavy making weird little sounds (I say he is whispering sweet little nothings in my ear!)and then he regurgitates. Flattering but gross- I have had him since he was a baby and I was very worried the first few times he did this. He is about 20 years old now and still does the same thing. I guess he isn't sick of me after all these years!
