In 1894, a lighthouse keeper named David Lyall arrived on Stephens Island off New Zealand with a cat named Tibbles. In just over a year, the Stephens Island Wren, a rare bird endemic to the island, was rendered extinct. Mounting scientific evidence confirms what many conservationists have suspected for some time--that in the United States alone, free-ranging cats are killing birds and other animals by the billions. Equally alarming are the little-known but potentially devastating public health consequences of rabies and parasitic "Toxoplasma" passing from cats to humans at rising rates. "Cat Wars" tells the story of the threats free-ranging cats pose to biodiversity and public health throughout the world, and sheds new light on the controversies surrounding the management of the explosion of these cat populations. This compelling book traces the historical and cultural ties between humans and cats from early domestication to the current boom in pet ownership, along the way accessibly explaining the science of extinction, population modeling, and feline diseases. It charts the developments that have led to our present impasse--from Stan Temple's breakthrough studies on cat predation in Wisconsin to cat-eradication programs underway in Australia today. It describes how a small but vocal minority of cat advocates has campaigned successfully for no action in much the same way that special interest groups have stymied attempts to curtail smoking and climate change. "Cat Wars" paints a revealing picture of a complex global problem--and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.

Today, according to the US Fish and Wildlife Service, more than fifty million Americans feed birds around their homes, and over the last sixty years, billions of pounds of birdseed have filled millions of feeders in backyards everywhere. Feeding Wild Birds in America tells why and how a modest act of provision has become such a pervasive, popular, and often passionate aspect of people’s lives. Each chapter provides details on one or more bird-feeding development or trend including the “discovery” of seeds, the invention of different kinds of feeders, and the creation of new companies. Also woven into the book are the worlds of education, publishing, commerce, professional ornithology, and citizen science, all of which have embraced bird feeding at different times and from different perspectives. The authors take a decade-by-decade approach starting in the late nineteenth century, providing a historical overview in each chapter before covering topical developments (such as hummingbird feeding and birdbaths). On the one hand, they show that the story of bird feeding is one of entrepreneurial invention; on the other hand, they reveal how Americans, through a seemingly simple practice, have come to value the natural world.

An expert in wildlife management tells the stories of those who are finding new ways for humans and mammalian predators to coexist. Stories of backyard bears and cat-eating coyotes are becoming increasingly common—even for people living in non-rural areas. Farmers anxious to protect their sheep from wolves aren’t the only ones concerned: suburbanites and city dwellers are also having more unwanted run-ins with mammalian predators. And that might not be a bad thing. After all, our government has been at war with wildlife since 1914, and the death toll has been tremendous: federal agents kill a combined ninety thousand wolves, bears, coyotes, and cougars every year, often with dubious biological effectiveness. Only recently have these species begun to recover. Given improved scientific understanding and methods, can we continue to slow the slaughter and allow populations of mammalian predators to resume their positions as keystone species? As carnivore populations increase, however, their proximity to people, pets, and livestock leads to more conflict, and we are once again left to negotiate the uneasy terrain between elimination and conservation. In The Predator Paradox, veteran wildlife management expert John Shivik argues that we can end the war while still preserving and protecting these key species as fundamental components of healthy ecosystems. By reducing almost sole reliance on broad scale “death from above” tactics and by incorporating nonlethal approaches to managing wildlife—from electrified flagging to motion-sensor lights—we can dismantle the paradox, have both people and predators on the landscape, and ensure the long-term survival of both. As the boundary between human and animal habitat blurs, preventing human-wildlife conflict depends as much on changing animal behavior as on changing our own perceptions, attitudes, and actions. To that end, Shivik focuses on the facts, mollifies fears, and presents a variety of tools and tactics for consideration. Blending the science of the wild with entertaining and dramatic storytelling, Shivik’s clear-eyed pragmatism allows him to appeal to both sides of the debate, while arguing for the possibility of coexistence: between ranchers and environmentalists, wildlife managers and animal-welfare activists, and humans and animals.
