In easter of 2021 I adopted my 13yo. cockatiel male from some of my family who had no idea how to care for a bird, he had a small cage, no toys, really smooth perches, not dowels but they were smoother than dowels, an all seed diet and a water bowl he couldn't fit in. I tried to bathe him a few times with a spray bottle when I first got him but he was terrified, and I got him a large water bowl and a large bowl on the bottom of his cage; I went in my room today and sprayed my other cockatiels to see how they'd respond the didn't much appreciate it, so I thought let me try Romeo and sure enough he started doing the bath dance. He let me spray him until he was nearly soaked. This bird probably hasn't had a bath in his whole life, I'm just so happy for him.
