"It exuded this particular scent also that was supposed to attract other kakapos," he says. Stolzenburg tells NPR's Renee Montagne that because its only predators were in the sky, the kakapo had no need to fly and, therefore, couldn't. One species Stolzenburg focuses on is the kakapo, a large, green, nocturnal parrot that is found only in New Zealand. In Rat Island: Predators in Paradise and the World's Greatest Wildlife Rescue, Stolzenburg gives an account of the damage done to island ecosystems by invasive species like cats, weasels and rats - all animals that have at one point overrun new island environments and nearly destroyed native species. But, as author William Stolzenburg writes in a new book, isolation can also be a weakness. The very word connotes isolation - an isolation that has allowed pockets of animal species to evolve in safety over the course of thousands of years.
