A funny story about the vacuum

[tawny30]

I am curious if this is true of everyone or just my birds!

Every time we vacuum both our red lored and our yellow collared macaw seem to think that means birdy bath time (laugh)
they happily start bathing in their water dishes (well Laura the amazon does since she has never picked up on the bottle) and Ringo (the macaw bathes with his water bottle until mom bought a clue and gave him something to bathe in before I take out the vacuum)
My only guess is that the sound reminds them of a shower or something but I think it is sooo cute!
