New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.

‘A vaulting triumph of a book’ Isabella Tree, author of Wilding 'A master storyteller, Weidensaul communicates so much joy in the sheer act of witnessing and such exhilaration in the advances of the science behind what he sees that we are slow to grasp the extent of the ecological crisis that he outlines.' Observer Bird migration remains perhaps the most singularly compelling natural phenomenon in the world. Nothing else combines its global sweep with its inherent ability to engender wonder and excitement. The past two decades have seen an explosion in our understanding of the almost unfathomable feats of endurance and complexity involved in bird migration – yet the science that informs these majestic journeys is still in its infancy. Pulitzer Prize-shortlisted writer-ornithologist Scott Weidensaul is at the forefront of this research, and A World on the Wing sees him track some of the most remarkable flights undertaken by birds. His own voyage of discovery sees him sail through the storm-wracked waters of the Bering Sea; encounter gunners and trappers in the Mediterranean; and visit a forgotten corner of north-east India, where former headhunters have turned one of the grimmest stories of migratory crisis into an unprecedented conservation success. As our world comes increasingly under threat from the effects of climate change, these ecological miracles may provide an invaluable guide to a more sustainable future for all species, including us. This is the rousing and reverent story of the billions of birds that, despite the numerous obstacles we have placed in their path, continue to head with hope to the far horizon.

The framework developed by Thomas A. Sebeok in his "global semiotics" is currently the most useful for investigating the nature and function of representation in human systems. The capacity to represent immediate reality is not unique to human animals, but the capacity to frame an indefinite number of possible worlds is unique to humans. This unique aspect of representational capacity in humans has led to "true culture," requiring a way to represent all the subtleties of language, in contrast to "nonhuman culture." It is on this level that nonverbal- and verbal-form assemblages blend together functionally and systematically. - from the Preface by Marcel Danesi This book proposes approaches to communication from different viewpoints. Their common objective is to contribute to what can be designated as Global Communication Studies. In our world, communication is all-pervasive. This calls for the broadest possible vision of the global sign network and an understanding of the sense of the role each of us must play in it. Consequently, the problem of communication is closely connected to the problem of responsibility. The book is dedicated to the late Thomas A. Sebeok.
