I just want to get a feel for the layout of the inside of the wall, especially where typical exits are, etc. Then I plan to have the bird hide somewhere inside it until nightfall. Under a bed, behind a dresser, etc. I figure he might at least be useful to create a diversion, or might even be able to get or keep a door open, or let us know before they start to open a door.
I guess I've gotten a pretty good idea of the layout, so he can just hide till dark.
