Great list and explanation,
@cherrynberry !
I'd like to add "Headlamp" to this list. It keeps your hands free to do what you need to do. I also highly recommend getting one with a red light. My birds aren't lap birds and aren't used to being handled. If I have to separate one, chasing it won't work because they're fast and I'm slow. I go in at night with the headlamp red light on. They know something is there, but don't get off the roost because they can't see well enough to know where they're going.
