Is there anything else Paco does when she does this? Maybe she isn't indicating what you think?
If she is doing this, where does she do it; (eg., your hand, your foot)? Wherever she chooses to do that, move her to somewhere else, like your lap, knee, or shoulder. Should she persist, place her on her playstand/perch. Ignore her for awhile, and try holding her again. Just repeat the process until she gets the point.
Also, it is important that you DO NOT give her an artificial 'companion'. Some people will place stuffed animals in the cage, causing further frustration for the hormonal bird.
