The Magpie In Relation To Agriculture

Two species of magpie feature in this book, the Black-billed Magpie, familiar to most Europeans, which occurs throughout much of the northern hemisphere, and the Yellow-billed Magpie, which is confined to California. Magpies are unmistakable in their appearance, voice and extrovert, arrogant manner. While their persecution at the hands of gamekeepers over the last hundred years has made them wary and difficult to approach, a number of recent field studies, both in Europe and North America, have successfully revealed the intricacies of the magpie way of life. Tim Birkhead has studied both species, and has produced a fascinating account of their ecology and behaviour. Many of the results from his ten-year study of magpies in northern England are published here for the first time. Particularly revealing however is his comparison of the two species and of their different races. Magpies occur in a wide range of habitats, including English farmland, the deserts of North America, the mountains of Saudi Arabia and the windswept plateaus of Tibet. As this book explains, magpies are able to exploit this diversity of habitats largely through their remarkably flexible social behaviour. The Magpies covers all aspects of their lives, including their marital relationships, food hoarding behaviour, longevity and survival, nesting behaviour, breeding success and their controversial relationship with man. The text is supported by numerous photographs, diagrams and tables, and superb illustrations by David Quinn.

One of the most striking and persistent ways humans dominate Earth is by changing land-cover as we settle a region. Much of our ecological understanding about this process comes from studies of birds, yet the existing literature is scattered, mostly decades old, and rarely synthesized or standardized. The twenty-seven contributions authored by leaders in the fields of avian and urban ecology present a unique summary of current research on birds in settled environments ranging from wildlands to exurban, rural to urban. Ecologists, land managers, wildlife managers, evolutionary ecologists, urban planners, landscape architects, and conservation biologists will find our information useful because we address the conservation and evolutionary implications of urban life from an ecological and planning perspective. Graduate students in these fields also will find the volume to be a useful summary and synthesis of current research, extant literature, and prescriptions for future work. All interested in human-driven land-cover changes will benefit from a perusal of this book because we present high altitude photographs of each study area.
