This book is an effort to explore the technical aspects associated with bird flight and migration on wings. After a short introduction on the birds migration, the book reviews the aerodynamics and Energetics of Flight and presents the calculation of the Migration Range. In addition, the authors explains aerodynamics of the formation flight and finally introduces great flight diagrams.
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.
Considers two parts of a project by artist Jill Magid that centers around flows of currency. Conceived as a story in multiple chapters, this book focuses on two parts of a larger project by artist Jill Magid in which she explores the circulation of pennies against the backdrop of the COVID-19 pandemic. Through Tender, a public artwork in New York City produced by Creative Time, and Tender: Balance, an exhibition at the Renaissance Society in Chicago, Magid both observes intimate financial and social transactions and delves into economic systems that are harder to see, intervening in the flows of currency in subtle, poetic ways. Along with visuals from these two parts of the project, the book offers insights into Magid's extensive research process and three new essays that provide greater social and art historical context for her work. In their contribution, Claire Bishop and Nikki Columbus consider how Magid's process makes wide-ranging connections to create a constellation of ideas. Jamilah King addresses the ongoing shift toward a cashless economy and who is left behind, and Aden Kumler explores histories of modifying currency. The book culminates in a conversation between the artist and curators Justine Ludwig and Karsten Lund, in which they reflect on the project's conceptual touchstones and on events contemporary to the work.

The authors follow the trail of one particular yellow butterfly, a butterfly with a notch on its wing whose journey begins in the Yucatan rain forest, and reach the shores of North America in a distance of more than 2,000 miles.
Marcel, a young tundra swan, tires halfway through the winter migration and stays behind while his parents and the flock continue south. He asks for advice from other animals about how to survive the winter, but their ways of living are not right for the swan. "For Creative Minds" section includes fun facts about tundra swans, migration, and an animal adaptation matching activity.
Scott Weidensaul follows hawks over the Mexican coastal plains, Bar-tailed Godwits that hitchhike on gale winds 7,000 miles nonstop across the Pacific from Alaska to New Zealand, and the Myriad Songbirds whose numbers have dwindled so dramatically in recent years.
Now a USA TODAY BEST-SELLER, The Sound of Wings is a masterfully crafted tale of love, friendship, betrayal, and the risks we take in the pursuit of justice. Seventy-year-old Goldie Sparrows faces declining finances, questionable health, and a late husband who torments her from the beyond. She seeks refuge in her butterfly garden, which is filled with voices and memories from long ago. Jocelyn Anderson is a struggling writer who finds escape from her custody battle in the journal of her late mother-in-law. As she gets pulled through the pages of time, Jocelyn discovers her own husband has a hidden history she knows nothing about. Is this secret now Jocelyn’s to keep? Krystal Axelrod is living a life she never dreamed she could have. And yet the demons of a dysfunctional childhood and mean girl culture from her cheerleading days cast their shadow over her ability to feel whole, capable, and worthy. Does Goldie hold the key to Krystal’s path to freedom?
A major proposal for a minor architecture, and for the making of spaces out of the already built. Architecture can no longer limit itself to the art of making buildings; it must also invent the politics of taking them apart. This is Jill Stoner's premise for a minor architecture. Her architect's eye tracks differently from most, drawn not to the lauded and iconic but to what she calls “the landscape of our constructed mistakes”—metropolitan hinterlands rife with failed and foreclosed developments, undersubscribed office parks, chain hotels, and abandoned malls. These graveyards of capital, Stoner asserts, may be stripped of their excess and become sites of strategic spatial operations. But first we must dissect and dismantle prevalent architectural mythologies that brought them into being—western obsessions with interiority, with the autonomy of the building-object, with the architect's mantle of celebrity, and with the idea of nature as that which is “other” than the built metropolis. These four myths form the warp of the book. Drawing on the literary theory of Gilles Deleuze and Félix Guattari, Stoner suggests that minor architectures, like minor literatures, emerge from the bottoms of power structures and within the language of those structures. Yet they too are the result of powerful and instrumental forces. Provoked by collective desires, directed by the instability of time, and celebrating contingency, minor architectures may be mobilized within buildings that are oversaturated, underutilized, or perceived as obsolete. Stoner's provocative challenge to current discourse veers away from design, through a diverse landscape of cultural theory, contemporary fiction, and environmental ethics. Hers is an optimistic and inclusive approach to a more politicized practice of architecture.
Rising from sandbars on the Platte River with clarion calls, the sandhill crane (Grus canadensis) feels the urgency of spring migration. Elegant, noble, and spiritual, the sandhill crane is one of the most ancient of all birds. More than a half-million strong, flying in squadrons, these majestic creatures point northward to their Arctic and sub-Arctic breeding ranges. Theirs is an epic story of endurance through the ages. With 153 stunning color photographs, On Ancient Wings presents sandhill cranes in their wild but increasingly compromised habitats today. Over the course of five years, Michael Forsberg documented the tall gray birds in habitats ranging from the Alaskan tundra, to the arid High Plains, from Cuban nature preserves to suburban backyards. With an eye for beauty and an uncommon persistence, the author documents the cranes' challenges to adapt and survive in a rapidly changing natural world. Forsberg argues that humankind, for its own sake, should secure the cranes' place in the future. On Ancient Wings intertwines the lives of cranes, people, and their common places to tell an ancient story at a time when sandhill cranes and their wetland and grassland habitats face daunting prospects.
