I have 3 macaws (2 b+g's, 1 greenwing) i just built a very large outdoor aviary and would like to add another bird. I was debating between an amazon and an umbrella cockatoo. I really would like the umbrella cockatoo, but have been reading a lot of cautionary tales about them (relentless constant screaming all the day long, feather plucking, etc). Could they possibly be that much louder or needy than my birds (very needy)? Any advice?
