This is such a great toy idea! It’s so neat how budgies can have preferences for certain kinds of play, like Picasso loving rotating things. I’ve noticed lately that my girl Luxie loves “plucking” at things to see them swing around, and likes ”springy” things. She does this with all her hanging toys, her swing, and sometimes my circular knitting needles—usually when I’m trying to use them! (Note for the curious: she is far more interested in the [stainless steel] needles than the yarn, but I am always watching when this happens to make sure she doesn’t ingest fibers, which could lead to a crop impaction. She keeps me on my toes!)
