Is it vomit or regurgitation?
Does she just lay it down somewhere for you(your hand, leg, on the desk, etc)?
If she's just throwing up and shaking her head(flinging it everywhere, it looks awful and it's gross. I promise.) then it could be a health/behavior thing.
I've heard of birds that get sick and throw up when they're scared/nervous, and even getting car sick!
It sounds more like the former though, she's trying to say "I love you! I brought you food!" It helps to distract her.
Keep foot toys on you when you handle her, and when you see the first signs of her regurgitating, give her a toy to take her attention elsewhere. We don't want her to think you're her mate, after all!
