Evolutionists have never been able to completely explain why birdsong is so inventive and why many species devote so many hours to singing. The standard explanations of defending territories and attracting mates don't begin to account for the variety and energy that the commonest birds exhibit. Is it possible that birds sing because they like to? This seemingly naive explanation is starting to look more and more like the truth. Why Birds Sing is a lyric exploration of birdsong that blends the latest scientific research with a deep understanding of musical beauty and form. Drawing on conversations with neuroscientists, ecologists, and composers, it is the first book to investigate the elusive question of why birds sing and what their song means to both avian and human ears. Whether playing his clarinet with the whitecrested laughing thrush in Pittsburgh, or jamming in the Australian winter breeding grounds of the Albert's lyrebird, Rothenberg immerses himself in the heart and soul of birdsong. He approaches the subject as a naturalist, philosopher, musician, and investigator. An intimate look at the mostlovely of natural phenomena, Why Birds Sing is a beautifully written exploration of a phenomenon that's at once familiar and profoundly alien.

    Deadly beauty. She turned her face towards me. The owl's massive facial disc produces a funnel for sound that is the most effective in the animal kingdom'Owls have captivated the human imagination for millennia. We have fixated on this night hunter as predator, messenger, emblem of wisdom, something pretty to print on a tote bag or portent of doom. Darlington sets out to tell a new story. Her fieldwork begins with wild encounters in the British Isles and takes her to the frosted borders of the Arctic. In her watching and deep listening to the natural world, she cleaves myth from reality and will change the way you think of this magnificent creature.

    1: Elementary Theory and Problems contains the essential material that is usually covered in required courses of strength of materials in our engineering schools. Strength of Materials - Part. 2: Advanced Theory and Problems contains the later developments that are of practical importance in the fields of strength of materials, and theory of elasticity. Complete derivations of problems of practical interest are given in most cases. The books are illustrated with a number of problems to which solutions are presented. In many cases, the problems are chosen so as to widen the field covered by the text and to illustrate the application of the theory in the solution of design problems.

    It is also peculiarly British in that it is deeply rooted in the British class system. Grouse shooting is big business, backed by powerful, wealthy lobbying groups, with tendrils running throughout British society.Inglorious makes the case for banning driven grouse shooting. Mark Avery explains why he has, after many years of soul-searching, come down in favor of an outright ban. There is too much illegal killing of wildlife, such as Buzzards, Golden Eagles, and, most egregiously of all, Hen Harriers; and, as a land use, it wrecks the ecology of the hills. However, grouse shooting is economically important, and it is a great British tradition. All of these, and other points of view, are given fair and detailed treatment and analysis, with testimony from a range of people on opposite sides of the debate.The book also sets out Avery's campaign with Chris Packham to gain support for the proposal to ban grouse shooting, culminating in "Hen Harrier Day," timed to coincide with the "Glorious" 12th. Ever controversial, Mark Avery is guaranteed to stir up a debate about field sports, the countryside, and big business in a book that all conservationists will want to read.

    Hailed as "unsinkable, " the "Kursk" was on maneuvers when mysterious explosions rocked the sub, causing it to sink to the bottom of the sea with its 118-man crew. This in-depth look at the disaster reveals previously unreleased information from family members of the deceased as well as from government officials.

    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. The Handbook also discusses how to create and use a field notebook, natural resource interpretation, citizen science, and collaborative conservation and serves as the primary text for the California Naturalist Program.

    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.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    There is the record-holding husband and wife who cross continents to "twitch" (spot rare birds); the disgraced "stringer" who takes desperate measures to falsify a spotting of the coveted black lark, leading hundreds on a fruitless search; and a group of friends who go birding in America only to be plagued by car trouble, drunk drivers, robbery, and an encounter with the border police.Birders is also an inspiring and heartwarming account of the author's lifelong love for his hobby, and the way it transforms him -- from his fetishistic love affair with his notebook and "bins" (binoculars) to his deep mourning for a friend who went missing when he followed the call of an elusive pheasant in the Himalayan mountains. Informative, touching, and astoundingly funny, here is the layman's invitation to share in an unlikely obsession.
