Mittu vs Bath vs Vacuum cleaner's noise Experiment in real time

It's a real time experiment I have done with my birds in the situation when Vacuum cleaner is on and creating noise. Noise triggers some kinds of sense in my Parrot's brains and telling them to go and have a good bath.Both Mittu and Charlie spreads their wings and walks around freely while it's happening. Watch video to see more.

Let me know if your parrots also have this kinds of weird sense and activities as I would love to hear about it.
