Weird behavior?

[Kikibird01]

My cockatiel hangs onto the side of the cage, holds her wing up on the side, and buries her head into her wing and kind of rubs her head into her wing. She grooms herself normally on her perch, but every so often she does this and I don’t know why?

my tiel does this when she is having a gentle spray shower. She moves her head under her wings , it looks like she cleans them. Maybe your tiel wants a shower

Yes, it could be the bath dance
