    By some estimates, we may already have lost almost half of the songbirds that filled the skies only forty years ago. Renowned biologist Bridget Stutchbury convincingly argues that songbirds truly are the "canaries in the coal mine"--except the coal mine looks a lot like Earth and we are the hapless excavators.Following the birds on their six-thousand-mile migratory journey, Stutchbury leads us on an ecological field trip to explore firsthand the major threats to songbirds: pesticides, still a major concern decades after Rachel Carson first raised the alarm; the destruction of vital habitat, from the boreal forests of Canada to the diminishing continuous forests of the United States to the grasslands of Argentina; coffee plantations, which push birds out of their forest refuges so we can have our morning fix; the bright lights and structures in our cities, which prove a minefield for migrating birds; and global warming. We could well wake up in the near future and hear no songbirds singing. But we won't just be missing their cheery calls, we'll be missing a vital part of our ecosystem. Without songbirds, our forests would face uncontrolled insect infestations, and our trees, flowers, and gardens would lose a crucial element in their reproductive cycle. As Stutchbury shows, saving songbirds means protecting our ecosystem and ultimately ourselves.Some of the threats to songbirds: - The U.S. annually uses 4-5 million pounds of active ingredient acephate, an insecticide that, even in small quantities, throws off the navigation systems of White-throated sparrows and other songbirds, making them unable to tell north from south. - The U.S. Fish and Wildlife Service conservatively estimated that 4-5 million birds are killed by crashing into communication towers each year.- A Michigan study found that 600 domestic cats killed more than 6,000 birds during a typical 10-week breeding season. Wood thrush, Kentucky warbler, the Eastern kingbird--migratory songbirds are disappearing at a frightening rate.

    Does it move us with its beauty? Can we make a living from it? But what if we examined a landscape on its own terms, freed from our expectations and assumptions?This is what celebrated writer Helen Humphreys sets out to do in this stunning, groundbreaking examination of place. For more than a decade Humphreys has owned a small waterside property on a section of the Napanee River in Ontario. In the watchful way of writers, she has studied her little piece of the river through the seasons and the years, cataloguing its ebb and flows, the plants and creatures that live in and round it, the signs of human usage at its banks and on its bottom.The River is the result, a gorgeous and moving meditation that uses fiction, non-fiction, natural history, archival maps and images, and stunning full-color photographs to get at the truth. In doing this, Humphreys has created a work of startling originality that is sure to become a new Canadian classic.

      Every spring, billions of birds sweep north, driven by ancient instincts to return to their breeding grounds. This vast parade often goes unnoticed, except in a few places where these small travelers concentrate in large numbers. One such place is along Lake Erie in northwestern Ohio. There, the peak of spring migration is so spectacular that it attracts bird watchers from around the globe, culminating in one of the world’s biggest birding festivals.     Millions of winged migrants pass through the region, some traveling thousands of miles, performing epic feats of endurance and navigating with stunning accuracy. Now climate change threatens to disrupt patterns of migration and the delicate balance between birds, seasons, and habitats. But wind farms—popular as green energy sources—can be disastrous for birds if built in the wrong places. This is a fascinating and urgent study of the complex issues that affect bird migration.

    As a young ornithology instructor at the Hog Island Audubon Camp, Dr. Stephen W. Kress learned that puffins had nested on nearby islands until extirpated by hunters in the late 1800s. To right this environmental wrong, he resolved to bring puffins back to one such island—Eastern Egg Rock. Yet bringing the plan to reality meant convincing skeptics, finding resources, and inventing restoration methods at a time when many believed in “letting nature take its course.” Today, Project Puffin has restored more than 1,000 puffin pairs to three Maine islands. But even more exciting, techniques developed during the project have helped to restore rare and endangered seabirds worldwide. Further, reestablished puffins now serve as a window into the effects of global warming. The success of Dr. Kress’s project offers hope that people can restore lost wildlife populations and the habitats that support them. The need for such inspiration has never been greater.

    While detailing this evolution, Humphries introduces us to synanthropy: The concept that animals can become dependent on humans without ceasing to be wild; they can adapt to the cityscape as if it were a field or a forest.Superdove simultaneously explores the pigeon's cultural transformation, from its life in the dovecotes of ancient Egypt to its service in the trenches of World War I, to its feats within the pigeon-racing societies of today. While the dove is traditionally recognized as a symbol of peace, the pigeon has long inspired a different sort of fetishistic devotion from breeders, eaters, and artists—and from those who recognized and exploited the pigeon's astounding abilities. Because of their fecundity, pigeons were symbols of fertility associated with Aphrodite, while their keen ability to find their way home made them ideal messengers and even pilots.Their usefulness largely forgotten, today's pigeons have become as ubiquitous and reviled as rats. But Superdove reveals something more surprising: By using pigeons for our own purposes, we humans have changed their evolution. And in doing so, we have helped make pigeons the ideal city dwellers they are today. In the tradition of Rats, the book that made its namesake rodents famous, Superdove is the fascinating story of the pigeon's journey from the wild to the city—the home they'll never leave.

    It is a hands-on guide to learning about the natural environment of California. Subjects covered include California natural history and geology, native plants and animals, California's freshwater resources and ecosystems, forest and rangeland resources, conservation biology, and the effects of global warming on California's natural communities.

    There they began a strenuous and thrilling hundred-day field trip around the edge of the continent. Part travelogue, part epic natural adventure, their richly illustrated record is "the superlatively good product of ideal circumstances" (Chicago Sunday Tribune).

    Thanks to the introduction of free-roaming cattle, ponies, pigs and deer – proxies of the large animals that once roamed Britain – the 3,500 acre project has seen extraordinary increases in wildlife numbers and diversity in little over a decade.Once-common species, including turtle doves, nightingales, peregrine falcons, lesser spotted woodpeckers and purple emperor butterflies, are now breeding at Knepp, and populations of other species are rocketing. The Burrells’ degraded agricultural land has become a functioning ecosystem again, heaving with life – all by itself.This recovery has taken place against a backdrop of catastrophic loss elsewhere. According to the 2016 ‘State of Nature’ report, the UK is ranked 29th in the world for biodiversity loss: 56% of species in the UK are in decline and 15% are threatened with extinction. We are living in a desert, compared with our gloriously wild past.In Wilding, Isabella Tree tells the story of the ‘Knepp experiment’ and what it reveals of the ways in which we might regain that wilder, richer country. It shows how rewilding works across Europe; that it has multiple benefits for the land; that it can generate economic activity and employment; how it can benefit both nature and us – and that all of this can happen astonishingly quickly. Part gripping memoir, part fascinating account of the ecology of our countryside, Wilding is, above all, an inspiring story of hope.

    It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity. Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    

    On the one hand wrens are ubiquitous. They are Britain's most common bird, with 8.5 million breeding pairs and have by far the loudest song in proportion to their size. They also thrive up and down Britain and Ireland: from the smallest city garden to remote offshore islands, blustery moors to chilly mountains. Yet many people, particularly a younger generation, are not sure if they have ever seen a wren. Perhaps because the wren is so tiny, weighing just as much as two A4 sheets of paper, and so busy, always on the move, more mouse than bird. However if we cast our eyes back to recent history wrens were a mainstay of literary, cultural and popular history. The wren was on postage stamps and the farthing, it featured in nursery rhymes and greetings cards, poems and rural `wren hunts', still a recent memory in Ireland particularly. With beautiful illustrations throughout, this captivating year-in-the-life biography reveals the hidden secrets of this fascinating bird that lives right on our doorstep.
