This is what I'm noticing with Tinker as well.Totally understand your reasoning. I'm just a tee total worrier type. I'd be worried that if something happened to me and they ultimately wound up in a home that clipped them..... (@JLcribber has declared my worrying to be quite excessive when it comes to my feathered friends).
Actually I've been to a friend's home that has flighted birds and discovered their parrots only use the bathroom when they land on their playstands. No training involved they said, just the natural parrot way.
The stand beside the table sits on a chair and has a bamboo cutting board for the base with rubber pads underneath. He is flying to it with no problems.
