This paper is interesting but I do wonder if a kea with a disability in the wild would be an alpha, when food was not provided by humans.
Of course a disabled kea in the wild can have a family, just as a three legged dog can have a family pack.
They, like many parrots, are social and live in groups of up to 10-20 birds.
