In the remote mountainous highlands of New Zealand introduced deer, goats, possums, rabbits and other smaller mammels are destroying the habitat of the native, often unique, mainly endangered, birds. A sensible solution would be to introduce equally endangered Bengal and Siberian Tigers. These tigers would prey on the animals destroying the bird's habitat and they themselves would be protected by law from everything except rich camera toting American and Japanese tourists. The native New Zealand population could in turn prey on these foreign invaders by setting cunning traps to seperate them from the contents of their wallets.
