I am watching a TV program that has a long scene with no sound except a waterfall.
The tiels got so excited and made a kind of joyful singing/chirping sound.
I should be sure ti spritx them tomorrow.

Lots of parrots like the sound of rain, and that's probably what it reminded them of. There are lots of reports about parrots getting excited when the owner runs the vacuum cleaner, and they think it's because the birds think it's raining.

Didn't know that.....we get so much rain
Here guess my birds think it's normal...LOL
