The 40 or so species of plover (genus Charadrius) offer key insights into ecological theory pertaining to many sub-disciplines. The editors have gathered international specialists to explore the many challenges faced by plovers.

The Northern Spotted Owl, a threatened species that occurs in coniferous forests in the western United States, has become a well-known environmental symbol. But how is the owl actually faring? This book contains the results of a long-term effort by a large group of leading researchers to document population trends of the Northern Spotted Owl. The study was conducted on 11 areas in the Pacific Northwest from 1985 to 2008, and its objectives were both to evaluate population trends and to assess relationships between reproductive rates and recruitment of owls and covariates such as weather, habitat, and the invasion of a closely related species, the Barred Owl. Among other findings, the study shows that fecundity was declining in five populations, stable in three, and increasing in three areas. Annual apparent survival rates of adults were declining in 10 out of 11 areas. This broad, synthetic work provides the most complete and up-to-date picture of the population status of this inconspicuous forest owl, which is at the center of the complex and often volatile debate regarding the management of forest lands in the western United States.

Reflecting the considerable research recently conducted, this book examines the 15 extant species of sea ducks that populate North America. It provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.

The Golden-winged Warbler is a migratory songbird that breeds in the temperate upper midwestern US (Wisconsin & Minnesota) and Canada (Manitoba) and winters in Central and northern South America. Its small breeding range has been shrinking due to habitat loss, competition and interbreeding. As a result of this disturbing trend, Golden-winged Warblers are being considered for listing as "threatened" or "endangered" under the Endangered Species Act. In preparation for potential listing, the book intends to bring together all the disparate sources information regarding this species.

The timing, duration, seasonality, extent and pattern of avian molt follows certain strategies. This book reviews and describes these strategies for nearly 200 species of birds from a 30-year study of Central Amazonian birds. Each account is to be illustrated with several color photos focusing on wing and tail feather molt.

The book demonstrates the power of ornithological collections to address key research questions at global scales through emerging new technologies, analytical techniques, and case studies. The book includes developing methods for making biological collections more accessible and "usable" for ornithological researchers.

This book is a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists regarding the Lesser Prairie-Chicken. It thoroughly reviews the life history, genetics, and ecology of the species and gives a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It provides a definitive reference for conservation researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.

The past decade has seen a huge increase in the interest directed toward sea ducks. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes. Reflecting the considerable research recently conducted, this book examines the 15 extant species of sea ducks that populate North America. It provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.

Exploring critical linkages between migratory birds, their seasonal resources, and shifts in climate change and weather events, this book brings together research on the current state of bird migration and phenology research in North America. It discusses the relation of the climate on wintering grounds to spring migration, the relationships of migratory birds and their seasonal resources, and the nature of these relationships in the face of climate change or extreme weather events. It also examines the USA-National Phenology Network¿s Nature¿s Notebook program, and ways in which these data can be incorporated into conservation research.

Reaching from interior Alaska across Canada to Labrador and Newfoundland, North America's boreal forest is the largest wilderness area left on the planet. This title brings together research on boreal bird biology and conservation. It highlights the importance of the region to the global avifauna.

Grouse - an ecologically important group of birds that include capercaillie, prairie chickens, and ptarmigan - are distributed throughout the forests, grasslands, and tundra of Europe, Asia, and North America. This title summarizes knowledge of grouse biology in 25 chapters contributed by 80 researchers from field studies around the world.
