Book excerpt: The status of the rich avifauna of western North America is ever changing in response to human influences, geomorphic processes, and natural climatic variation. Documenting and synthesizing the patterns, rate, and causes of these changes is crucial for the conservation of birds in this region, particularly in a time of rapid climate change, expanding human population, and accelerated resource extraction. To that end, a symposium on avifaunal change was held at Western Field Ornithologists' annual conference in San Diego, California, in October 2014, which formed the basis for the current volume. The papers herein emphasize the overarching themes of the effects of extensive habitat loss and degradation on the avifauna of the West in the 19th and 20th centuries and the responses of birds to environmental change and variation. Several papers portray rays of hope, documenting reversals of trends in the loss of some important habitats, the recovery of some avian populations in response to management, and resiliency in other species as they adapt to novel habitats. Others express increasing concern for the potential future effects of a rapidly changing climate. Most emphasize the importance of long-term monitoring of the population trends, distribution, and ecological attributes of the region's birdlife. The geographical representation and bird species or groups covered varies widely. Collectively these papers should aid in the long-term conservation of the region's birdlife.--

Available in PDF, EPUB and Kindle. Book excerpt: Now that more than half of the world’s population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world’s expanding metropolises.

Download or read book Greater Sage Grouse written by Steve Knick and published by Univ of California Press. This book was released on 2011-05-19 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: Admired for its elaborate breeding displays and treasured as a game bird, the Greater Sage-Grouse is a charismatic symbol of the broad open spaces in western North America. Unfortunately these birds have declined across much of their range—which stretches across 11 western states and reaches into Canada—mostly due to loss of critical sagebrush habitat. Today the Greater Sage-Grouse is at the center of a complex conservation challenge. This multifaceted volume, an important foundation for developing conservation strategies and actions, provides a comprehensive synthesis of scientific information on the biology and ecology of the Greater Sage-Grouse. Bringing together the experience of thirty-eight researchers, it describes the bird’s population trends, its sagebrush habitat, and potential limitations to conservation, including the effects of rangeland fire, climate change, invasive plants, disease, and land uses such as energy development, grazing, and agriculture.

Download or read book Video Surveillance of Nesting Birds written by Christine Ann Ribic and published by Univ of California Press. This book was released on 2012-05-13 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Until recently, inferring identities of predators and monitoring cryptic behaviors at the nest was time-consuming, often with anecdotal results. No more. Video nest surveillance, so aptly revealed in this volume, has ushered in a new era of data collection that allows field workers to link environmental factors with such aspects as the temporal dynamics of predator communities in relation to what the birds are doing at their nests, thus removing much of the guesswork of earlier studies.”--Spencer G. Sealy, University of Manitoba "Video Surveillance of Nesting Birds shatters earlier beliefs about how birds interact with nest predators. Much of what we thought we knew about nesting and its hazards was flat-out wrong, as authors in this book discovered by using modern technology in the field. As simple as we would like our models of animal behavior to be, this book shows that reality is far more complex and nuanced."--Douglas H. Johnson, University of Minnesota

Download or read book Emerging Avian Disease written by Ellen Paul and published by Univ of California Press. This book was released on 2012-05-02 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, new human disease pandemics, arising from animals stimulated by ongoing environmental change, demonstrate the value of ornithological research into avian diseases. A group of 29 researchers addresses a diverse set of topics, including the evolutionary and ecological aspects of the host-vector systems, the effects of genetic variation, introduction success and vector ecology, evolution of resistance and virulence of pathogens, and the effects of changing geographic distributions. In addition to empirical studies under field conditions, the authors present predictive models to assess the movement and potential impact of these diseases. Other chapters delve into the potential impacts of pathogens and the key role of biosurveillance and documenting impacts of disease on bird populations.
