In order for Alala to have any chance of survival in the wild, caretakers have to hunt and remove ALL predators of the Alala in the entire area, including killing the hawk birds that kill the Alala.  Cats, rats, predatory birds, etc all have to be removed.  Eventually the hawks will return and the caretakers have to keep on removing these birds.  Sounds cruel but it is the only way for Alala to survive in the wild.
