Did my Conure regurgitate or throw up?

I am having a hard time telling but I am concerned. My brown-throat Conure bobbed her head a few times before spitting up a clear fluid. Is she okay? What does this mean? The vet was unhelpful, offered no advice and has us on a waitlist.

That is regurgitation.
