You have lots Owls and other birds of prey which I love .
The problem with Greys and few other larger parrots is that they are very intelligent and thus can become very destructive, self destructive in captivity .
The solution here is an outdoor aviary if the parrot becomes self destructive but at that point , they will never be that tame once they get used to outside .
I love the conures and rather long lived for little parrots . A friend has sun and half moons . They are inside birds .
