    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.

    Her reward for the grueling work of rescuing birds—such as feeding baby hummingbirds every twenty minutes all day long—is her empathy with them and the satisfaction of knowing the world is a birdier and more beautiful place. The Bluebird Effect is about the change that's set in motion by one single act, such as saving an injured bluebird—or a hummingbird, swift, or phoebe. Each of the twenty five chapters covers a different species, and many depict an individual bird, each with its own personality, habits, and quirks. And each chapter is illustrated with Zickefoose's stunning watercolor paintings and drawings. Not just individual tales about the trials and triumphs of raising birds, The Bluebird Effect mixes humor, natural history, and memoir to give readers an intimate story of a life lived among wild birds.

    Phoebe Snetsinger had planned to be a scientist, but, like most women who got married in the 1950s, she ended up keeping house, with four kids and a home in the suburbs by her mid-thirties. Numb and isolated, she turned to bird-watching, but she soon tired of the birds near home and yearned to travel the world. Then her life took a crushing turn: At forty-nine, she was diagnosed with cancer and told that she had less than a year to live. Devastated, she began crisscrossing the globe, finding rare and spectacular birds that brought her to the heights of spiritual ecstasy. But as it turned out, she beat the cancer. She eventually went to more than a hundred countries, had frequent brushes with danger, became a hero in the birding world, and set a record for the most species seen. Life List is a powerful portrait of a woman who found refuge from society’s expectations in a dangerous and soul-stirring obsession.

    He describes in very human terms 475 years of recorded history in the Palmetto State, including the experiences of all South Carolinians--those with roots in Africa and in Europe as well as Native Americans; male and female; rich and poor. In an eminently readable presentation, Edgar uses letters, diaries, and other writings to let voices from the past take part in telling the state's fascinating story.Recounting the period from the first Spanish exploration to the end of the Civil War, Edgar charts South Carolina's rising national and international prominence and its parallel economic ascendancy. He dispels myths about the state's early history--including the notion that the colony was inhabited by a homogeneous white population--and tells how South Carolina developed an agricultural economy that relied heavily on African American slave labor. Edgar examines, among other topics, the impact of the American revolution, Charleston's significance as a metropolis and major seaport, and the state's leadership in the Secession movement.With changes wrought by the Civil War, South Carolina slipped from national prominence into a period marked by economic, social, civil, and political strife. Edgar details the everyday life of blacks and whites during Reconstruction, the state's mixed efforts to join the New South, and Benjamin Ryan Tillman's rise to power. He also chronicles South Carolina's changing politics in the once-solid South, the state's reawakening after World War II, the casualties and victories of an extended civil rights struggle, and the Palmetto State's present economic, educational, and political challenges.

    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.

    What defines her work is her skill with plants and her ability to create a garden that responds to the history of the site and the wider landscape.

The styles vary considerably – logical, calm, beautiful, romantic, naturalistic, formal, sometimes spare – but the principles remain firm. Jinny designs for the long term, with consideration for the environment; these gardens are built to last.Reflecting Jinny‘s highly individual character, there is plenty of wit and quirkiness alongside the expert knowledge, and it will appeal to the widest audience of garden lovers. Thoughtful and beautiful, yet practical and informative, this book marries artistry with functionality.

    But every time they think they've finally closed the door, the bird makes an unexpected appearance. It happened in the 1920s, and it’s happened in almost every subsequent decade. For more than 60 years, each sighting has been met with ridicule and scorn. Respected researchers and naturalists have been branded as quacks just for having the temerity to say that the ivory-bill still exists. Yet the reports still trickle in. Is there any truth to these sightings, or are they just a case of wishful thinking, misidentification, or outright fabrication? To unravel the mystery, author Tim Gallagher heads south, deep into the eerie swamps and bayous of the vast Mississippi Delta, searching for people who claim to have seen this rarest of birds and following up—sometimes more than 30 years after the fact—on their sightings. He meets a colorful array of characters: a cigar-chomping ex-boxer who took two controversial pictures of an alleged ivory-bill in 1971; a former corporate lawyer who abandoned her career to search for ivory-bills full time; two men who grew up in the ivory-bill’s last known stronghold in a final remnant of primeval forest in Louisiana. With his buddy Bobby Harrison, a true son of the South from Alabama, Gallagher hits the swamps, wading through hip-deep, boot-sucking mud and canoeing through turgid, mud brown bayous where deadly cottonmouth water moccasins abound. In most cases, they are clearly decades too late. But when the two speak to an Arkansas backwoods kayaker who saw a mystery woodpecker the week before and has a description of the bird that is too good to be a fantasy, the hunt is on. Their Eureka moment comes a few days later as a huge woodpecker flies in front of their canoe, and they both cry out, “Ivory-bill!” This sighting—the first time since 1944 that two qualified observers positively identify an ivory-billed woodpecker in the United States—quickly leads to the largest search ever launched to find a rare bird, as researchers fan out across the bayou, hoping to document the existence of this most iconic of birds.

     From the Aztec plumed serpent to the Christian dove to Plato's vision of the human soul growing wings, religion and philosophy use birds to represent our aspirational selves. Winged creatures appear in mythology and folk tales, and in literature by writers as diverse as Ovid, Thoreau, and T. S. Eliot. They've been omens, allegories, and guides; they've been worshipped, eaten, and feared. Birds figure tellingly in the work of such nature writers as Gilbert White and Peter Matthiessen, and are synonymous with the science of Darwin.Gibson spent years collecting this gorgeously illustrated celebration of centuries of human response to the delights of the feathered tribes. The Bedside Book of Birds is for everyone who is intrigued by the artistic forms that humanity creates to represent its soul.
