Hello, you have a beautiful bird. A good piece of advice to you is to never hit the cage to make that noise. PLEASE DON'T EVER DO THAT. You are only going to have a scared bird and it will greatly affect her health. You can instead talk calmly to it, and do other gentle activities with it. Please don't misunderstand me. I know from experience. Enjoy your bird. It is a true Blessing. Stay Blessed.
