Well for me the creature comes out when everyone is home and pretty much done going in and out. Nerd never tried to escape so we were more lax with him and he couldn't fly well and knew it, plus he was perfectly happy with his life. If we were home he was out till he decided to go to bed, which he usually did on his own.
Lurch could fly so we tried to be more careful and let him out when we were home and done but one day he was out and sister decided not to chase him around to put him away and sneak out seeing how I think he was sleeping, she came home, still sleeping so she tried to sneak in and he woke up and flew over to see her and out the door he went. SO with Dobby seeing how he's a acrobatic jet of a bird we make sure everyone's done for the day and out he comes. So if we're not ready to deal with him being a wild boy or both of us aren't home yet he's in but once everything is settled he gets out till we go to bed. They all were mostly quiet because they knew the routine and had things to do in thew cage when they weren't snoozing and waiting for us to come home. Usually if they hear somebody come home they start flock calling and making happy noises getting excited that their flock mates are home and they get to come out and hang out wherever they pleased as long as it wasn't hurting anything.
Nerd could hear the sound of my old car a block away and would start stretching and calling and if he was out I had to run in and try to catch him before he dove down the side of the cage and looked at me like you missed me again
Lurch would get excited then have to plop on me and ride into the bathroom while I cleaned up so he could get drinks and play in the water from the faucet. Dobby is usually a bit more subdued and stretches and makes noises to himself and waits for us to all get settled so he can come out. Then he zooms around and lands on the couch to get treats while we eat.
If their routine was changed or things didn't happen when they knew the should they could get noisy complaining about not doing what was supposed to happen. They do exactly know when you normally come home, what you car sounds like, or noises you make while coming to the door and usually wake up and get ready to greet their family.
Nerd used to flock call and make noises in the mornings if the sun had come out which made him happy, then maybe a bit in the evening but they all would get noisy if they felt they were being ignored or something seemed wrong to them.
