That naughty little Lemon Drop!
For now, it has become his routine, and “his” place to sit. How dare you shoo him from his place is what he is thinking
He won’t like sitting somewhere else at first, but if he has no choice, he should eventually adjust if you’re consistent. It might be a bit frustrating but little by little he’ll learn. Be patient because it may take some time. Try putting your head down and putting your arm up where your forearm is across your forehead area. Don’t let him get to the area he likes. He will protest and get upset, but just ignore that and keep on turning and blocking your face.
Does he love millet or have a favorite treat? I wouldn’t expect him to willingly land where you want him to right away, but when he eventually lands on your arm or shoulder, praise and treat. Position your body so that your arm is really the only place he has room to land. Once he’s used to sitting there, you can straighten your arm and let him climb to your shoulder. Usually if your arm is angled with your hand lower than your shoulder, it’s natural for them to climb upwards.
Good luck Goldenwing, and keep us posted!
