DIVThe decline of bird species in a wide range of North American habitats—forests, prairies, shrublands, mountain regions, marshes, and deserts—has inspired two decades of intense scientific study of bird ecology and conservation. But for professional scientists and amateur birders alike, interpreting the results of these diverse studies is often complex and bewildering. This accessible book pulls together recent research on bird species and habitats to show how basic ecological principles apply in seemingly different situations. Robert A. Askins provides an engaging introduction to bird ecology and concepts of landscape ecology, focusing on such intriguing species as Bachman’s Warbler, Red Crossbill, Mountain Plover, and Marbled Murrelet. Understanding the ancient landscapes of North America and how humans have changed them, Askins says, is essential for devising plans to protect and restore bird populations. In addition to such obvious changes to the landscape as the clearing of forests and plowing of prairies, more subtle changes also dramatically affect birds. Species may disappear when we interrupt natural disturbances by suppressing wildfires or trapping out beaver, or when we disrupt habitat with roads and housing developments. Askins challenges some of the assumptions that underlie current conservation efforts and offers concrete recommendations, based on sound ecological principles, for protecting the rich natural diversity of North America’s birds./div

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.

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.
