According to the theory, the remaining inhabitants then were decimated during a cannibalistic civil war in about 1650.

A year ago life for Cook’s petrel chicks on Little Barrier (Hauturu) was bleak and short lived. Now, less than a year after the operation to rid the island of rats, most chicks have survived to fly from their burrows.
