Book Description
Molt is an important avian life history event in which feathers are shed and replaced. The timing, duration, seasonality, extent and pattern of molt follows certain strategies and this book reviews and describes these strategies for nearly 190 species based on information gathered from a 30-year study of Central Amazonian birds. Most species accounts are illustrated with several color photos focusing on wing and tail feather molt, molt limits, and how to use these patterns to accurately age birds. Published in collaboration with and on behalf of the American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series is a rich source of life history information for ornithologists working on tropical birds.

Book Description
For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds’ beauty and extraordinary diversity, but also their importance to ecosystems worldwide. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms. In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services—the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation. Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions—all seen through the lens of human well-being—to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.

Book Description
A leading figure in the emerging field of extinction studies, Thom van Dooren puts philosophy into conversation with the natural sciences and his ethnographic encounters to vivify the cultural and ethical significance of modern-day extinctions. Unlike other meditations on the subject, Flight Ways incorporates the particularities of real animals and their worlds, drawing philosophers, natural scientists, and general readers into the experience of living among and losing biodiversity. Each chapter of Flight Ways focuses on a different species or group of birds: North Pacific albatrosses, Indian vultures, an endangered colony of penguins in Australia, Hawaiian crows, and the iconic whooping cranes of North America. Written in eloquent and moving prose, the book takes stock of what is lost when a life form disappears from the world—the wide-ranging ramifications that ripple out to implicate a number of human and more-than-human others. Van Dooren intimately explores what life is like for those who must live on the edge of extinction, balanced between life and oblivion, taking care of their young and grieving their dead. He bolsters his studies with real-life accounts from scientists and local communities at the forefront of these developments. No longer abstract entities with Latin names, these species become fully realized characters enmeshed in complex and precarious ways of life, sparking our sense of curiosity, concern, and accountability toward others in a rapidly changing world.

Book Description
Millions of people know a little bit about efforts to save the whooping crane, thanks to the movie Fly Away Home and annual news stories about ultralight planes leading migratory flocks. But few realize that in the spring of 1941, the population of these magnificent birds--pure white with black wingtips, standing five feet tall with a seven-foot wingspan--had reached an all-time low of fifteen. Written off as a species destined for extinction, the whooping crane has made a slow but unbelievable comeback over the last seven decades. This recovery would have been impossible if not for the efforts of Robert Porter Allen, an ornithologist with the National Audubon Society, whose courageous eight-year crusade to find the only remaining whooping crane nesting site in North America garnered nationwide media coverage. His search and his impassioned lectures about overdevelopment, habitat loss, and unregulated hunting triggered a media blitz that had thousands of citizens on the lookout for the birds during their migratory trips. Allen's tireless efforts changed the course of U.S. environmental history and helped lead to the passage of the Endangered Species Act in 1973. Though few people remember him today, his life reads like an Indiana Jones story, full of danger and adventure, failure and success. His amazing story deserves to be told.

Book Description
How a small group of New York biologists brought the peregrine falcon and bald eagle back from the brink of extinction. In the late 1970s, the bald eagle and the peregrine falcon were heading toward extinction, victims of the combined threats of DDT, habitat loss, and lax regulation. Flight Paths tells the story of how a small group of New York biologists raced against natures clock to bring these two beloved birds back from the brink in record-setting numbers. In a narrative that reads like a suspense tale, Darryl McGrath documents both rescue projects in never-before-published detail. At Cornell University, a team of scientists worked to crack the problem of how to breed peregrine falcons in captivity and then restore them to the wild. Meanwhile, two young, untested biologists tackled the overwhelming assignment of rebuilding the bald eagle population from the states last nesting pair, one of whom (the female) was sterile. McGrath interweaves this dramatic retelling with contemporary accounts of four at-risk species: the short-eared owl, the common loon, the Bicknells thrush, and the piping plover. She worked alongside biologists as they studied these elusive subjects in the Northeasts most remote regions, and the result is a story that combines vivid narrative with accessible science and is as much a tribute to these experts as it is a call to action for threatened birds. Readers are taken to a snow-covered meadow as an owl hunts her prey, a loon familys secluded pond, an eagle nest above the Hudson River, and a mountaintop at dusk in search of the Bicknells thrush, one of the planets rarest birds. Combining a little-known chapter of New Yorks natural history with a deeply personal account of a lifelong devotion to birds, Flight Paths is not only a story of our rapidly changing environment and a tribute to some of New Yorks most heroic biologists, but also a captivating read for anyone who has ever thrilled to the sight of a rare bird. In Flight Paths Darryl McGrath weaves together science, politics, personal struggle, and the emotional gravity of permanent loss into poignant tales of survival. She reminds us that our actions and determination can have a huge impact on birds and other wildlife that make their homes in the Adirondack Park. She brings a fresh perspective to modern conservation efforts and reminds us why birds matter in our everyday lives. Anyone who loves the Adirondack Park, or just appreciates wild places, will enjoy reading this book. William C. Janeway, Executive Director, Adirondack Council Not since David R. Zimmermans To Save a Bird in Peril has there been a popular book on rare and endangered birds so well researched and documented as this one. McGrath writes the story of the remarkable restoration of our national bird in New York, a saga that is largely the story of a few unique people who devoted their lives to this endeavor. She writes similar stories about the peregrine falcon, the common loon, the Bicknells thrush, and the short-eared owl, emphasizing the special problems and solutions for each species. Anyone interested in the details of what it takes to save rare or endangered species from extinction should read this sympathetic and well-written book. Tom J. Cade, Founding Chairman and Director, The Peregrine Fund In Flight Paths, Darryl McGrath tells the compelling story of New Yorks legacy as a national and international innovator in modern bird conservation. In an engaging style that often reads more like a novel than typical historical reporting, she focuses on the successful efforts to save the peregrine falcon and bald eagle from extinction in the Lower 48 states. Her conversations and field experience with the dedicated scientists and conservationists whose tireless efforts brought these magnificent birds back from the brink bring a rare depth and richness to the narrative. The pioneering work described in this well-told tale give some hope that when courageous and innovative scientists simply refuse to take no for an answer, seemingly intractable problems will yield.
