This book was released on 2021-03-30 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Download or read book Toward A Minor Architecture written by Jill Stoner and published by MIT Press. This book was released on 2012-03-09 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "You are a rare bird, easy to see but invisible just the same." That thought is close at hand in Sparrow Envy: Field Guide to Birds and Lesser Beasts, as renowned naturalist and writer J. Drew Lanham explores his obsession with birds and all things wild in a mixture of poetry and prose. He questions vital assumptions taken for granted by so many birdwatchers: can birding be an escape if the birder is not in a safe place? Who is watching him as he watches birds? With a refreshing balance of reverence and candor, Lanham paints a unique portrait of the natural world: listening to cicadas, tracking sandpipers, towhees, wrens, and cataloging fellow birdwatchers at a conference where he is one of two black birders. The resulting insights are as honest as they are illuminating.

Book excerpt: This “vividly imagined and well-written novel” (Booklist, starred review) tells a gripping story about a boy from Scotland and a girl from West Africa who join together to save a migrating Osprey—and end up saving each other. When Callum spots crazy Iona McNair on his family’s sprawling property, she’s catching a fish with her bare hands. She won’t share the fish, but does share something else: a secret. She’s discovered a rare endangered bird, an Osprey, and it’s clear to both her and Callum that if anyone finds out about the bird, it, and its species, is likely doomed. Poachers, egg thieves, and wild weather are just some of the threats, so Iona and Callum vow to keep track of the bird and check her migratory progress using the code a preservationist tagged on her ankle, no matter what. But when one of them can no longer keep the promise, it’s up to the other to do it for them both. No matter what. Set against the dramatic landscapes of Scotland and West Africa, this is a story of unlikely friendships, the wonders of the wild—and the everyday leaps of faith that set our souls to flight.

Download or read book No Way Home written by David S. Wilcove and published by Island Press. This book was released on 2012-09-26 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Download or read book On Ancient Wings written by Michael Forsberg and published by University of Nebraska Press. This book was released on 2004 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Border and Rule written by Harsha Walia and published by Haymarket Books. This book was released on 2021-02-09 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Border and Rule, one of North America’s foremost thinkers and immigrant rights organizers delivers an unflinching examination of migration as a pillar of global governance and gendered racial class formation. Harsha Walia disrupts easy explanations for the migrant and refugee crises, instead showing them to be the inevitable outcomes of the conquest, capitalist globalization, and climate change that are generating mass dispossession worldwide. Border and Rule explores a number of seemingly disparate global geographies with shared logics of border rule that displace, immobilize, criminalize, exploit, and expel migrants and refugees. With her keen ability to connect the dots, Walia demonstrates how borders divide the international working class and consolidate imperial, capitalist, and racist nationalist rule. Ambitious in scope and internationalist in orientation, Border and Rule breaks through American exceptionalist and liberal responses to the migration crisis and cogently maps the lucrative connections between state violence, capitalism, and right-wing nationalism around the world. Illuminating the brutal mechanics of state formation, Walia exposes US border policy as a product of violent territorial expansion, settler-colonialism, enslavement, and gendered racial ideology. Further, she compellingly details how Fortress Europe and White Australia are using immigration diplomacy and externalized borders to maintain a colonial present, how temporary labor migration in the Arab Gulf states and Canada is central to citizenship regulation and labor control, and how racial violence is escalating deadly nationalism in the US, Israel, India, the Philippines, Brazil, and across Europe, while producing a disaster of statelessness for millions elsewhere. A must-read in these difficult times of war, inequality, climate change, and global health crisis, Border and Rule is a clarion call for revolution. The book includes a foreword from renowned scholar Robin D. G. Kelley and an afterword from acclaimed activist-academic Nick Estes.

Download or read book Wings over the Great Plains Bird Migrations in the Central Flyway written by Paul Johnsgard and published by Lulu.com. This book was released on 2012-11-19 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Central Flyway has been recognized as a collective North-South migratory pathway centered on the North American Great Plains for nearly a century, but it has never been analyzed as the species that most closely follow it, or the major stopping points used by those species on their journeys between their northern breeding and southern wintering grounds. A total of 114 U.S. and 21 Canadian localities of special importance to birds migrating within the Central Flyway are identified and described in detail. Judging from available regional, state and local information, nearly 400 species of 50 avian families regularly use the Central Flyway during their migrations. Nearly 90 Central Flyway species have wintering areas parly extending variably far into the Neotropic zoogeographic realm, and at least 50 of these winter entirely within the Neotropic realm. A few of these species undertake some of the longest known migrations of all birds, in excess of 8,000 miles in each direction. Seven maps, 49 figures and over 100 literature citations are included."--Abstract.
