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.

"On the Wing is the first book to take a comprehensive look at the evolution of flight in all four groups of powered flyers: insects, pterosaurs, birds, and bats."--Book jacket.

Originally published 40 years ago, this book uses vivid illustrations and simple rhyming text by a noted author/illustrator to introduce the concept of shapes and sizes to curious young readers as he suggests how they can view the world in a new and exciting way. Full-color illustrations.

The airplane ranks as one of history's most ingenious and phenomenal inventions--and surely one of the most world-shaking. How ideas about its aerodynamics first came together and how the science and technology evolved to forge the airplane into the revolutionary machine it became is the epic story James R. Hansen tells in The Bird Is on the Wing. Just as the airplane is a defining technology of the twentieth century, aerodynamics has been the defining element of the airplane. Hansen provides an engaging, easily understandable introduction to the role of aerodynamics in the design of such historic American aircraft as the DC-3, X-1, and 747. Recognizing the impact individuals have had on the development of the field, he conveys not only a history of aircraft technology, but also a collective biography of the scientists, engineers, and designers who created the airplanes. From da Vinci, whose understanding of what it took to fly was three centuries too early for practical use, to the invention of the airplane by the Wright brothers, Hansen explores the technological matrix from which aeronautical engineering emerged. He skillfully guides the reader through the development of such critical aerodynamic concepts as streamlining, flutter, laminar-flow airfoils, the mythical "sound barrier," variable-sweep wing, supersonic cruise, blended body, and much more. Hansen's explanation of how vocabulary and specifications were developed to fill the gap between the perceptions of pilots and the system of engineers will fascinate all those interested in how human beings have used aerodynamics to move among, and even beyond, birds on the wing.

This book is specifically for high school students, though it is useful to college students and anyone interested in the art and craft of poetry. Koch and Farrell, experienced teachers as well as poets, write about poetry in such a way that students will find it accessible and interesting. The book includes selections of poetry by twenty-three poets, among them Dickinson, Hopkins, Pound, Williams and Eliot, as well as Ginsberg, O'Hara, Baraka and Ashbery. There is also the translated work of such modern European poets such as Lorca, Rilke, Rimbaud, Apollinaire and Mayakowsky.
