I have a bird room and a house that my three parrots fly through all day long. I am retired so we spent oodles of time together. In the birdroom they are safe because they have lots of perches and toys and no exposed wiring or cables, etc. I do leave they alone in their bird room. For some reason they do not fight in their "nest." The rest of the house they will get into battles in. I have to be very careful about my keyboards and any cereal or other foods that I leave out on the counter, kitchen table, refrigerator top, etc. etc. They are very curious and always hungry birdies. I do have a cargo net, a very large and heavy one in my office and there are lots of swings and boings hanging throughout the abode. It works for me, but then I live alone and I am retired so my time is my birdies' time.
