Book excerpt: The New York Times–bestselling author of H is for Hawk explores the human relationship to the natural world in this “dazzling” essay collection (Wall Street Journal). In Vesper Flights, Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing the massive migration of songbirds from the top of the Empire State Building, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk’s poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds’ nests, and the unexpected guidance and comfort we find when watching wildlife.

Book excerpt: "Flight is the essence of birdness. I strive to illustrate the beauty and complexity of avian flight." -- Peter Cavanagh 100 Flying Birds: Photographing the Mechanics of Flight offers a vivid and varied glimpse into the world of birds. A white-tailed eagle plummeting through a Japanese sky, a brown pelican striking a silhouette against an Ecuadorian sunset, an Atlantic puffin carrying its fish dinner above the Scottish coast, or a keel-billed toucan gliding through a Costa Rican jungle canopy; readers will marvel at the splendor of birds in flight while learning the techniques to capture these gravity-defying moments from a world-class nature photographer. For each picture, author and photographer Peter Cavanagh shares his most evocative thoughts: the challenges of the shoot, the beauty of the location, and the curiosities of the species. Bird people will enjoy the bird photographs and facts, travelers will gobble up the tales of distant parts, and photographers will absorb the technical details. For instance, readers might be surprised to see that a very slow shutter speed can freeze the motion of hummingbird wings. Peter Cavanagh has collected 100 beautiful photos spanning a wide range of species. The subjects of each of the 11 chapters are: Eagles Hummingbirds Gulls and Terns Small Waterbirds Large Waterbirds Ducks, Geese and Swans Raptors Condors and Corvids Cranes Songbirds Favorites

Available in PDF, EPUB and Kindle. Book excerpt: P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Available in PDF, EPUB and Kindle. Book excerpt: LECTURING BIRDS ON FLYING For the past few decades, the financial world has often displayed an unreasonable willingness to believe that "the model is right, the market is wrong," in spite of the fact that these theoretical machinations were largely responsible for the stock market crash of 1987, the LTCM crisis of 1998, the credit crisis of 2008, and many other blow-ups, large and small. Why have both financial insiders (traders, risk managers, executives) and outsiders (academics, journalists, regulators, the public) consistently demonstrated a willingness to treat quantifications as gospel? Nassim Taleb first addressed the conflicts between theoretical and real finance in his technical treatise on options, Dynamic Hedging. Now, in Lecturing Birds on Flying, Pablo Triana offers a powerful indictment on the trustworthiness of financial theory, explaining—in jargon-free plain English—how malfunctions in these quantitative machines have wreaked havoc in our real world. Triana first analyzes the fundamental question of whether financial markets can in principle really be solved mathematically. He shows that the markets indeed cannot be tamed with equations, presenting a long and powerful list of obstacles to prove his point: maverick unlawful human actions rule the markets, unexpected and unimaginable events shape the markets, and historical data is not necessarily a trustworthy guide to the future of the markets. The author then examines the sources of origin of many prevalent theories and mathematical dictums. He details how the field of financial economics evolved from a descriptive discipline to an abstract one dedicated to technically concocting professors' own versions of how such a world should work. He goes on to explain how Wall Street and other financial centers became eager employers of scientists, and how scientists became eager employees of financial firms. Triana concludes with an in-depth discussion of the most significant historical episodes of theory-caused real-life market malaise, with a strong emphasis on the current credit crisis. In the end, Lecturing Birds on Flying calls for the radical substitution of good old-fashioned common sense in place of mathematical decision-making and the restoration to financial power of those who are completely unchained to the iron ball of classroom-obtained qualifications.
Download or read book Modelling the Flying Bird written by C.J. Pennycuick and published by Elsevier. This book was released on 2008-08-23 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and is the skeleton around which the book is built. The book provides a wider background and then explains how Flight works and shows how to set up and test hypotheses generated by the program. The book and the program are based on adapting the conventional (and well-tested) thinking of aeronautical engineers to the biological problems of bird flight. Their primary aim is to convince biologists that this is the appropriate way to handle problems that involve flight, to make the engineering background accessible to biologists, and to provide a tool kit in the shape of the Flight program, which they can use to solve practical problems involving bird flight and migration. In addition, the book will be readily accessible to engineers who want to know how birds work, and should be of interest to the ever-growing community working on flapping "micro air vehicles" (MAVs). The program can be used to predict the flight performance and capabilities of reconstructed fossil birds and pterosaurs, flying in ancient atmospheres that differ from present conditions, and also, of course, to predict and account for the results of experiments and observations on living birds and bats. * An up to date work by the world's leading expert on bird flight * Examines the biology and biomechanics of bird flight with added reference to the flight of bats and pterosaurs. * Uses proven aeronautical principles to help solve biological issues in understanding and predicting the flight capabilities of birds and other vertebrates. * Provides insights into the evolution of flight and the likely capabilities of extinct birds and reptiles. * Gives a detailed explanation of the science behind, and use of, the author's predictive bird flight simulation program - Flight - which is available on a companion website. * Presents often difficult concepts in easily understood language.

Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
