Book Description
A flock of Pinyon Jays arrive in a flash of blue, and leave again just as suddenly. This once mysterious bird is now the subject of over 20 years of intensive research involving over one thousand colour-marked jays by Russell Balda, John Marzluff and their colleagues and helpers. This plain blue bird has turned out to be anything but plain in its biology and behaviour. Uniquely dependent on the seeds of the Pinyon Pine for food, they have developed a number of behavioural and morphological adaptations to best utilise this resource, above all caching enough seeds each autumn to supply their needs throughout the winter and fuel their unusual habit of nesting in late winter. Fluctuations in pine-seed supply, both by season and between years, poses special problems for these birds and has led to their extremely flexible and complex social system in which learning and memory play an unusually large part. They store pine seeds and retrieve them with uncanny accuracy; they form lifelong pair bonds and nest colonially, occasionally involving younger birds to help established pairs rear the young; and they use their large vocabulary to coordinate activities within one of the largest known avian societies. This intriguing story will fascinate both the enthusiastic amateur birder and the professional alike. Packed with information, it presents Pinyon Jay biology in a readable form and places them into the wider context of studies on bird ecology and evolution. Fine illustrations by Tony Angell, with additional pictures by Caroline Bauder, complete this attractive addition to any birder's bookshelf.

Book Description
Until now there has been no single, comprehensive resource on the status of North America's most threatened birds and what people can do to help protect them. Birder's Conservation Handbook is the only book of its kind, written specifically to help birders and researchers understand the threats while providing actions to protect birds and their habitats. Jeffrey Wells has distilled vast amounts of essential information into a single easy-to-use volume-required reading for anyone who loves birds and wants to ensure they are protected. At-a-glance species accounts cover in detail North America's one hundred most at-risk birds; each account is beautifully illustrated by today's top bird artists. The text includes status, distribution, ecology, threats, conservation actions and needs, and references. A distribution map accompanies each entry. Chapters discuss birds as indicators of environmental health, the state of North American bird populations, major conservation issues, and initiatives now underway to improve the health of North America's birds. Birder's Conservation Handbook is an indispensable resource for birdwatchers, researchers, naturalists, and conservationists. Reading it will inspire you to become an active steward of our birds and the habitats we share. A comprehensive guide to North America's one hundred most at-risk birds and how to protect them Compact and easy to use, with beautiful illustrations and data organized for convenient, at-a-glance reference Detailed species accounts, including distribution maps Practical advice on conservation Information on leading conservation agencies and resources

Book Description
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Book Description
Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems. Contributors to the volume consider both direct and indirect effects of widlife-recreationist interactions, including: wildlife responses to disturbance, and the origins of these responses how specific recreational activities affect diverse types of wildlife the human dimensions of managing recreationists the economic importance of outdoor recreation how wildlife and recreationists might be able to coexist The book is a useful synthesis of what is known concerning wildlife and recreation. More important, it addresses both research needs and management options to minimize conflicts.

Book Description
The time is ripe to investigate similarities and differences in the course of social evolution in different animals. This book brings together renowned researchers working on sociality in different animals to deal with the key questions of sociobiology. For the first time, they compile the evidence for the importance of ecological factors in the evolution of social life, ranging from invertebrate to vertebrate social systems, and evaluate its importance versus that of relatedness.

Book Description
This Non-timber Forest Products' assessment serves as a baseline science synthesis and provides information for managing non-timber forest resources in the United States. This report provides technical input to the 2017 National Climate Assessment and closely follows the Intergovernmental Panel on Climate Change (IPCC) process. You will find an overview of the findings and interrelated discussions covering aspects of biophysical, social, cultural, economic, and policy dimensions of non-timber forest products and the implications of the effects of climatic variabilities and change for them. Appendix information summarizes non-timber forest products relative to geographic regions across the country.
