Anna, if you got most of it off Sprite's beak, I'm pretty sure there's no harm done, because what little acetone (nail polish solvent) he may have sniffed, would have been severely diluted by the surrounding air.....and the little bit that got on his tongue would have been enough to keep him from trying more & more than probably not enough to do more than give him a bad taste.....
It might be best to make sure Sprite is caged from now on when you're doing your nails and/or toes.....
Smile.....he'll be OK.....you were fast enough to get almost all of it off.....
