So, I think nobody has a reason now to doubt the credibility of the phenomenon you've described. According to the information skramer contributed and according to what Dave says about your Maggys, it seems unlikely that your birds feel irritated by spectral components > 20kHz.
Then again, who on earth can claim that he knows *all* about how a bird's perception works?
Can you place a mic by the bird cage, record the signal, and analyze the spectrum? Maybe the cause is a side effect like, say, an oscillating amp or some sort of IM distortions and your birds get bothered by that.Manfred
