This volume draws on research on bird species and their habitats to explain how basic principles of bird ecology and landscape ecology can help us create scientifically sound plans for protecting and restoring the rich diversity of North American birds. This edition includes an afterword that reviews literature that has appeared since the first edition was completed in 1999. This new material - on such key issues as the importance of preserving large expanses of natural habitat, the importance of maintaining early successional habitats, and the habitat requirements of neotropical migrants - shows how the research on landscape ecology of birds has shaped conservation policy more rapidly than most would have predicted.

Despite the potential synergy that can result from basing management applications on results from research, there is a polarization of cultures between wildlife managers and wildlife researchers. Wildlife Science: Connecting Research with Management provides strategies for bridging cultural and communication gaps between these groups. Contributors present case studies highlighting the role of state and federal agencies and private organizations in management and research; the lingering disconnects between grassland birds, quail, and deer research and management; as well as the development of management techniques from field research, rangelands management, and ranch management. Case Studies: The Disconnect between Quail Research and Quail Management Sage-Grouse (Centrocercus urophasianus) and the Disconnect between Research and Management on Public Lands in the American West Ecological Goals, not Standardized Methods, are needed to Create and Maintain Habitat for Grassland Birds A Historic Perspective of the Connectivity between Waterfowl Research and Management Deer in the Western United States Whitetail deer (Odocoileus virginianus) in the Eastern United States Impacts of Wind Energy Development on Wildlife: Challenges and Opportunities for Integrated Science, Management, and Policy The Role of Joint Ventures in Bridging the Gap between Research and Management Developing Management Strategies from Research: the Pushmataha Forest

The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole’s sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.

Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.

The North American Grouse Their Biology And Behavior

This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating "leks," arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. The book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

"The atlas is a monumental achievement. This book is a must for everyone interested in birds, Ontario, and the natural world."-- Margaret Atwood and Graeme Gibson, author ofThe Bedside Book of Birds The most authoritative and up-to-date resource on the birds of Ontario. Ontario's boreal forest is the breeding area for most of North America's songbirds. More than 3,000 birders contributed to this book by surveying the province from Lake Erie to Hudson's Bay. With 400 color photographs, the atlas provides detailed information on the distribution and population status of all the birds that breed in Ontario, which then migrate all over the continent. The 900 maps illustrate and record the breeding population for all the species and their range changes since the first atlas was published 20 years ago. Special "new abundance" maps and population estimates for many species reveal how numbers vary across the province's vast and diverse landscape. The atlas reveals the 10 most populous species in Ontario: Nashville warbler Chipping sparrow Dark-eyed junco Golden-crowned kinglet Magnolia warbler White-throated sparrow Yellow-rumped warbler American robin Red-eyed vireo Swainson's thrush. Among the interesting discoveries these birders brought to light: the Canada goose and the house finch experienced the greatest increases in population, and the common nighthawk and chimney swift experienced the greatest decreases. The Atlas of the Breeding Birds of Ontario is the definitive reference for birders, biologists and any general reader with an interest in nature and the state of the environment.
