Wingless buzzard on his new place

The first day in a new place. The bird hid in a house and he does not want to come out of there. I decided not to scare him with the camera, I just carefully set the bowl of food. Despite the fact that the bird began to eat on its own, the adaptation process is difficult. I know that time and patience will help, but I really feel sorry for him. Unfortunately, I can never put it together with other birds, because the lack of wings creates balance problems. In addition, in winter he will have to live indoors.
