I am going to try the bell thing with Percy and Lizzie, it is getting more and more difficult to get them in at night, they just sit up on the rope perch that is about a foot down from the ceiling and stare down at me as if to say "Can't get us up here"You can also train Chiri to return to his cage without stepping up.
I have several untamed budgies that go back in their cage because I've used positive reinforcement training to teach them they will get a reward when they do so.
Initially, when I was ready for them to go back in the cage I would first dim the lights and pull down the shades in the room. If the radio or TV was on, I turned it off.
Then I would stand by their cage and ringing the bell on one of their toys while telling them, "It's time to go in your cage now!"
Once they went back into the cage, they were given a small bit of millet.
This method worked well and they now go in the cage when asked to do so without the lights being dimmed or the blinds lowered and the TV or radio can stay on.
Getting the millet reward is the best part of "going back home"
