We've run a rescue and an aviary in the past and currently have about 30 feathered friends( down from 300). We have 3 B&G so we've been there. If the macaw thinks she can buffalo, she will. Do not ,whatever you do, let her be at or above eye level, it's a "who is on the higher perch thing". I promise, she can sense fear as well as any dog. True story, the first time ever going to the house belonged to my wife( dating before the ring), she brought the B&G of hers out and introduced me...that dang bird promptly nailed me....to show me I was not wanted anywhere near her owner...well, that went on about 2 years. I could not even be in the same room when she was out as she would come at me with claws out, wings flapping and jaws snapping.... Well we had several macaws, green wing, my baby, a rescue harlequin and this dang B&G...We had built a flight for them and one day, it just felt right, I walked out there, put out my arm and said "UP Murphy" and we've been good every since (about 10 years)
