The inspiring story of David Wingate, a living legend in the conservation movement, who brought the Bermuda petrel back from presumed extinction. David Wingate is known throughout Bermuda as the "birdman" and in the international birding and conservation community as a "living legend" singlehandedly responsible for bringing back a species of sea bird thought to have been extinct for 400 years. Bermuda once served as the nesting ground for millions of cahows, a nocturnal petrel that comes ashore only to breed and incubate their young. But after the islands were settled their population was decimated, and by 1620 they were gone. Or so it was thought until one showed up in the 1950s and David Wingate, then but 15 years old and already a budding ornithologist was invited along to seek its origin.
