Book excerpt: At the heart of this book by Nobel Prize–winning immunologist and professor Peter Doherty is this striking observation: Birds detect danger to our health and the environment before we do. Following a diverse cast of bird species around the world—from tufted puffins in Puget Sound to griffon vultures in India, pigeons in East Asia, and wedge-tailed shearwaters off the islands of Australia’s Great Barrier Reef—Doherty illuminates birds’ role as an early warning system for threats to the health of our planet and our own well-being.Their Fate Is Our Fate is an impassioned call not only to attention but to action. As “citizen scientists” we can collect data, vital to cutting-edge research, that depends on the birds that are all around us. Armed with our observations, scientists will continue to uncover new ways to glimpse our future in birds—and to affirm how, truly, their fate is our fate.
