Soaring on African Wings by Hendrik Erasmus Pdf

The prologue of this autobiography gives an idea of the flowing, almost esoteric, prose and original poetry which surfaces throughout the story. A highly authentic and richly textured account is given of life as a white English- speaking youngster raised in rural South Africa during the 1960's and 1970's. A vivid account is given of life in the military, duty in the jungles of the Caprivi on the Zambesi river and political awareness attained at Law School. Employment as a banker,salesman, cabdriver, wine-maker, goldminer, labourer, legal man. Surviving encounters with knifemen, wild animals and beautiful women. The South American diary chronicles an extraordinary backpacking/cycling saga, taking the reader from the jungles of the Amazon into the lives of the vibrant South American people in the raw 1980's. Travelling, teaching English and experiencing the rich cultures of Greece, South Korea, and Thailand. Unforgettable experiences in Laos and the Philippines. Near death in Taiwan. There is true depth and honesty in the writing which is easy to read and digest, with real humour and pathos presented in the telling. The strong friendships that are formed, and the life lessons that are learned, are presented with love for the people and increasing self-knowledge. The writer keeps the reader entranced by skillfully juxtaposing different periods in time, thereby establishing a theme of motion which never lets up.

Modelling the Flying Bird by C.J. Pennycuick Pdf

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.

Soaring Skyward by Claudine Burnett Pdf

Flying was a perilous adventure, with death only a small breath away. Many lost their lives in pursuit of their dream and have remained relatively forgotten, until now. (italics until now) Aviation fever struck young and old alike, especially after the four Dominguez Air Meets held in Southern California between 1910-1913. It inspired many such as the Birnie and French brothers, Charles Day, and Glenn Martin to build their own air ships. For others like Frank Champion, Long Beachs first airman, it meant learning from the best---traveling to London, England, to study with Louis Bleriot, and going on to teach others, such as Long Beach Airport founder Earl Daugherty, to fly. There were also daring women: Tiny and Ethel Broadwick, who parachuted out of airplanes when many men refused to do so because they considered it too dangerous; Gladys ODonnell instrumental in founding the Womens Air Derby; World War II ferrying pilots, led by Barbara Erickson London, whose service to America was not recognized until 1977; Dianna Bixby and Joan Merriam Smith trying to complete Amelia Earharts dream of circumnavigating the globe. Soaring Skyward (italics for title) introduces remarkable men and women who embraced the dangers and challenges of flight. It also tells the story of the Long Beach Municipal Airport, the center of much of Southern Californias aviation history. The early days of ballooning, air circuses, parachute jumps, barnstorming, air meets, forgotten military sites and much more are all explored in this well documented look into the past, and future, of aviation in Southern California. After twenty years of extensive research, Ms. Burnetts book is sure to open up new sources of information for aviation and history enthusiasts, and most definitely shed additional light on the past.

Movement And Locomotion In Animals by A. Kumar Pdf

Movement and locomotion are collectively called the biomechanics, which is the science that brings Biology and mechanical engineering together. It is the liveliest and most fascinating branch and deals with the study of animal locomotion: how birds fly and fishes swim, how slugs crawl, how legged animal (and people) run, and much else besides. The bewildering variety of styles of movement used by creatures ranging in size from amoeba to whales presents innumerable challenges to biomechanicists.

The Handbook of Bird Identification by Mark Beaman,Steve Madge Pdf

An identification guide covering all the bird species to have occurred in the European region. Birding is one of the most popular activities and pastimes in Europe and so it follows that it is essential to be able to identify the birds on view, be it in the back garden or for making more serious in-depth studies. This book aims to bring together as much information as possible in one volume, using extremely detailed, up-to-date guides and identification of every species known to have occurred in Europe and the West Palearctic, that is, the whole of Europe, North Africa as far south as the Central Sahara, the Middle East to the border of Iran, the Azores, Madeira, Canary Islands, the islands off Mauritania and the Cape Verde islands, as defined by Cramp and Simons 1977. They have certainly been successful in doing so and have produced a wonderfully comprehensive guide covering nearly 900 species, showing a wide range of differing plumages. The colour plates are exquisite and have been painted by some of Europe's leading bird artists. The text is clear and can be followed by beginners but finer points of identification are included for the benefit of more serious bird watchers. Particularly helpful is the cross-referencing of the text and colour plates. There are more than 600 colour maps to identify where the birds are to be found, which are simple and easy to use with excellent descriptions of status and habitat.

Flight Identification of Raptors of Europe, North Africa and the Middle East by Dick Forsman Pdf

Raptors are notoriously hard to identify, even if seen well, and represent perhaps the toughest of all ID challenges for birders. This book is the ultimate flight-identification guide for the raptors of the Western Palaearctic, covering Europe, North Africa, the Middle East (including Arabia) to Central Asia. It provides identification information for all 60 species that regularly occur in the region, to subspecific level. The text covers every plumage and age in detail, with each species account accompanied by a range of photographs covering all the principal plumages. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts.

African Raptors by William S. Clark,Rob Davies Pdf

The most comprehensive guide to African raptors ever published. Due to its large land mass and impressive variety of habitats, Africa has the most diverse range of raptors of any continent – with almost a third of the world's species occurring in the region. These diurnal birds of prey are well known for their hooked bill and powerful talons, as well as their keen vision that enables them to accurately detect their prey during flight. This authoritative guide, part of the Helm Identification series, features all 106 species found in Africa, with particular emphasis on their field identification. Encompassing falcons, eagles, ospreys, kites, vultures and more, African Raptors discusses the identification of both perched and flying birds, bringing together the very latest research with accurate distribution maps, more than 300 colour photographs and 52 superb plates that illustrate a broad range of ages and racial plumage differences. This book is the ultimate reference on these remarkable birds, and will be indispensable for all birders and ornithologists with an interest in birds of prey.

Locomotion of Animals by Alexander Pdf

This book is about how animals travel around on land, in water and in the air. It is mainly about mechanisms of locomotion, their limitations and their energy requirements. There is some information about muscle physiology in Chapter 1, but only as much as seems necessary for the discussions of mechanisms and energetics. There is information in later chapters about the patterns of repetitive movement involved, for instance, in different gaits, but nothing about nervous mechanisms of coordination. I have tried to include most ofthe widely-used methods of locomotion, but have not thought it sensible to try to mention every variety of locomotion used by animals. This book is designed for undergraduates, but I hope that other people will also find it interesting. It is possible and sometimes illuminating to use complex mathematics in discussions of animal locomotion. This book includes many equations, but little mathematics. Such mathematics as there is, is simple. Discussions of the mechanisms and energetics of locomotion inevitably involve mechanics. I expect that some readers will know a lot of mechanics, and some hardly any. I have tried to help the latter without boring the former, by putting a summary of the necessary mechanics in an appendix (p. 140). References from the main text to the appendix will tell readers where they can find help, if they need it. Figures and equations in the appendix have numbers distinguished by a prefix A (for instance, Figure A.3).
