Book Description
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.

Book Description
Colin Powell once observed that "a dream doesn't become reality through magic; it takes sweat, determination, and hard work." This sentiment is mirrored dramatically in the story of African Americans in aerospace history. The invention of the airplane in the first decade of the twentieth century sparked a revolution in modern technology. Aviation in the popular mind became associated with adventure and heroism. For African Americans, however, this new realm of human flight remained off-limits, a consequence of racial discrimination. Many African Americans displayed a keen interest in the new air age, but found themselves routinely barred from gaining training as pilots or mechanics. Beginning in the 1920s, a small and widely scattered group of black air enthusiasts challenged this prevailing pattern of racial discrimination. With no small amount of effort—and against formidable odds—they gained their pilot licenses and acquired the technical skills to become aircraft mechanics. Over the course of the twentieth century and into the twenty-first, African Americans have expanded their participation in both military and civilian aviation and space flight, from the early pioneers and barnstormers through the Tuskegee airmen to Shuttle astronauts. Featuring approximately two hundred historic and contemporary photographs and a lively narrative that spans eight decades of U.S. history, Black Wings offers a compelling overview of this extraordinary and inspiring saga.

Book Description
Half a century before the 'flying wing' B-2 stealth bomber entered service, John K. 'Jack' Northrop was already developing prototypes of a large 'flying wing' strategic bomber, which would have been the most radical bombers of their age. World War II brought a need for very long-range bombers and Northrop received a contract for a 172-ft span bomber, the B-35. Several of these were built, gradually evolving into the definitive XB-35 configuration. Testing revealed that the aircraft was invisible to radar, but engineers struggled to overcome the design challenges and several pilots were lost in crashes. While the program was cancelled in the 1950s, the concept extended into other highly innovative areas, such as the XP-56 and MX-324 Rocket Wing prototype fighters. But the greatest legacy was the first operational flying wing – the Northrop Grumman B-2 stealth bomber, which used much of the hard-won experience from the pioneering programs of half a century before.

Book Description
There is a common but often unspoken arrogance on the part of outside observers that folk science and traditional knowledge—the type developed by Native communities and tribal groups—is inferior to the “formal science” practiced by Westerners. In this lucidly written and humanistic account of the O’odham tribes of Arizona and Northwest Mexico, ethnobiologist Amadeo M. Rea exposes the limitations of this assumption by exploring the rich ornithology that these tribes have generated about the birds that are native to their region. He shows how these peoples’ observational knowledge provides insights into the behaviors, mating habits, migratory patterns, and distribution of local bird species, and he uncovers the various ways that this knowledge is incorporated into the communities’ traditions and esoteric belief systems. Drawing on more than four decades of field and textual research along with hundreds of interviews with tribe members, Rea identifies how birds are incorporated, both symbolically and practically, into Piman legends, songs, art, religion, and ceremonies. Through highly detailed descriptions and accounts loaded with Native voice, this book is the definitive study of folk ornithology. It also provides valuable data for scholars of linguistics and North American Native studies, and it makes a significant contribution to our understanding of how humans make sense of their world. It will be of interest to historians of science, anthropologists, and scholars of indigenous cultures and folk taxonomy.
