Ever since yesterday, he has been screeching around night time. The thing is, he only screeches at one side of the cage. He would run to the left side of the cage, stick his beak out, and screech towards the kitchen. Then, he'd run back to the right side quietly, and a few seconds later, he'd run back to the left side. Is this normal behavior? Or should I be concerned? He also seems frightened. Should I move his cage somewhere else?
