It's fun to hear about routines for others birds and their antics. I do bed for my bird by covering her cage and then turning out the light in that room (my study). It is really half of the living room, so she is not far form where I usually sit. I often watch TV on my computer after she has been put to bed. She doesn't seem to mind it at all and usually doesn't move around much once I cover her.
It is good to hear that your birds are well-adjusted and happy.
