Not OP but of some bird owners I've see that let their birds hang out in their house / on their shoulders and such the birds willingly go to their cage to rest.
That's a little different, no? A cage that is open that you can willingly access and leave versus being locked in a cage.
+1 to this. My birds all have open cage doors and they mostly stay in their cage. That's where their food and water is, and they only come out of their cage to go into another one
