This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration. It deals with all aspects of this absorbing subject, including the problems of navigation and vagrancy, the timing and physiological control of migration, the factors that limit their populations, and more. Author, Ian Newton, reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe, including current climate change. This adventurous book places emphasis on ecological aspects, which have received only scant attention in previous publications. Overall, the book provides the most thorough and in-depth appraisal of current ...

How and why birds navigate the skies, travelling from continent to continent xe2x80x94 flying thousands of miles across the earth each autumn and spring xe2x80x94 has continually fascinated the human imagination, but only recently have we been able to fully understand these amazing journeys. How did this revolution come about? Flight Paths is the never-before-told story of how an eccentric group of ornithologists, engineers and other pioneering scientists have harnessed nearly every technological development of the last hundred years to understand bird migration in detail - from where and when they take off, their flight paths and behaviours, their destinations and the challenges they face getting there. In this fascinating and compelling story Rebecca Heisman uncovers the secret history of an ornithological arms race that not only helped solve the mystery of bird migration using radar, radioactive isotopes, satellites and the humble aluminium band but has also given us much needed insight into how best to protect and conserve the bird life we cherish.
The generation of electricity by wind energy has the potential to reduce environmental impacts caused by the use of fossil fuels. Although the use of wind energy to generate electricity is increasing rapidly in the United States, government guidance to help communities and developers evaluate and plan proposed wind-energy projects is lacking. Environmental Impacts of Wind-Energy Projects offers an analysis of the environmental benefits and drawbacks of wind energy, along with an evaluation guide to aid decision-making about projects. It includes a case study of the mid-Atlantic highlands, a mountainous area that spans parts of West Virginia, Virginia, Maryland, and Pennsylvania. This book will inform policy makers at the federal, state, and local levels.
