Population Status of Raptors

Urban Raptors


Book Description

Raptors are an unusual success story of wildness thriving in the heart of our cities—they have developed substantial populations around the world in recent decades. But there are deeper issues around how these birds make their urban homes. New research provides insight into the role of raptors as vital members of the urban ecosystem and future opportunities for protection, management, and environmental education. A cutting-edge synthesis of over two decades of scientific research, Urban Raptors is the first book to offer a complete overview of urban ecosystems in the context of bird-of-prey ecology and conservation. This comprehensive volume examines urban environments, explains why some species adapt to urban areas but others do not, and introduces modern research tools to help in the study of urban raptors. It also delves into climate change adaptation, human-wildlife conflict, and the unique risks birds of prey face in urban areas before concluding with real-world wildlife management case studies and suggestions for future research and conservation efforts. Boal and Dykstra have compiled the go-to single source of information on urban birds of prey. Among researchers, urban green space planners, wildlife management agencies, birders, and informed citizens alike, Urban Raptors will foster a greater understanding of birds of prey and an increased willingness to accommodate them as important members, not intruders, of our cities.




Status Reports on Twelve Raptors


Book Description

Depletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes.




Population Ecology of Raptors


Book Description

Dr Newton's book is concerned with all aspects of population regulation in diurnal birds of prey, their social behaviour, dispersion, numbers, movements, breeding and mortality. He has drawn on his own studies in Scotland and on material and investigations worldwide to produce an authoritative and stimulating synthesis of current thinking and research on the ecological problems of the Falconiformes. He also deals in detail with the effects of pesticides and other pollutants on these birds, and with their scientific management and conservation. The author's lucid style will ensure a wide readership among research workers and the more general audience with an interest in birds of prey. There is a full bibliography and an extensive appendix of tables.

The Raptors of Arizona


Book Description

Thousands of birdwatchers come to Arizona each year seeking rare or intriguing species, and for those watching the skies the additional sighting of a bird of prey is a reward in itself. The Grand Canyon state boasts the most dramatic assortment of raptors in North America: hawks, eagles, falcons, kites, and owls, plus vultures and condors. Here can be found nearly all the raptor species of the continental United States and also established populations of species associated with Mexico, such as the Gray Hawk, Common Black-Hawk, Zone-tailed Hawk, and Whiskered Screech-Owl. Arizona's raptors are found in an unrivaled diversity of habitats, from saguaro cactus forests where tiny Elf Owls nest to the Vermilion Cliffs, where the gigantic California Condor was introduced in 1996. Yet many species live in habitats that are now jeopardized by degradation or development, making an understanding and appreciation of raptors crucial to their survival. The Raptors of Arizona brings together the knowledge and insights of 29 raptor and wildlife authorities who provide original information and syntheses on Arizona's 42 raptor species, with an emphasis on aspects of their natural history in Arizona. A chapter on each bird includes its description, a range map, and information on its distribution, habitat, life history, and status. Additional chapters cover conservation, habitats, where and when to watch raptors, and the sport of falconry. The book is enhanced by 42 full-color illustrations by Richard Sloan, one of the premier wildlife artists in North America, whose paintings were commissioned by the Arizona Wildlife Foundation specifically for this project. Co-published with the Arizona Game and Fish Department




Raptors of North America


Book Description

From majestic Bald Eagles to tiny Elf Owls, raptors are nature’s most fascinating and powerful birds. As predators with wide ranging habitats and food sources, raptors also serve as a litmus test for the health of their ecosystems. To preserve a species such as the Everglade Kite or Spotted Owl is to ensure the survival of many other creatures. Ornithologists Noel and Helen Snyder have spent nearly fifty years studying and photographing birds of prey in their natural habitat. The result of decades of firsthand field studies combined with key biological and conservation studies by other experts, Raptors of North America presents a comprehensive and captivating account of our continent’s birds of prey. Readers will meet the nocturnal raptors, the owls, and the diurnal raptors: hawks, harriers, kites, falcons, eagles, ospreys, vultures, and condors. This book was an editor's choice of the Scientific American Book Club.







Migrating Raptors of the World


Book Description

"Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel."--BOOK JACKET.




Population Limitation in Birds


Book Description

This book meets the demand for a comprehensive introduction to understanding the processes of population limitation. Recognized world-wide as a respected biologist and communicator, Dr. Ian Newton has now written a clear and detailed treatise on local scale population limiting factors in birds. It is based almost entirely on results from field studies, though it is set in a contemporary theoretical framework. The 16 chapters fall under three major section headings: Behavior and Density Regulation; Natural Limiting Factors; and Human Impacts. Population Limitation in Birds serves as a needed resource expanding on Dr. David Lacks research in this area of ornithology in the 1950s. It includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie. - Provides a sorely needed introduction to a long-established core subject in ornithology - Focuses on local scale factors - Written by a well-known biologist and effective communicator - Includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie
