    Carl Jones' love for animals began in his childhood. As a boy, he rescued injured wild creatures. In the 1970s, when the 24-year-old biologist learned that the Mauritius kestrel(红隼) is dying out, he decided to do his part.

He arrived on the island in an age of extinction. Even his employers of BirdLife International instructed him to “pull out elegantly” and leave the kestrel-saving to Mauritius government officials. That actually meant closing it down, because the Mauritians didn’t have the resources or ability.

Despite various difficulties, Jones holds the belief that all species are savable and humans need to live closely with other species. He has done so all his life and developed his hands-on approach to saving species.

Jones challenges the classic conservation wisdom that we must first understand the reasons for a species, decline and restore its habitat. Instead, he argues that scientists must identify the limiting factors on a species' population—food, nesting sites, competition, killing, disease—with practical fieldwork. “If there's a shortage of food, you will start feeding. If there's a shortage of nesting sites, you will put up nesting boxes. You don't need endless PhD students studying a species for 20 years. ” Conservation science, he argues, is often too remote. “Do you sit back and monitor a sick patient or do you treat them and see what works? A lot of species have been studied to extinction. ”

In Mauritius, Jones has preserved many plant species and nine animals. Without Carl Jones, the world might have lost the Mauritius kestrel, the pink pigeon and more.
