The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

This report identifies the more important known migratory bird habitat areas and sites within the provinces of Alberta, Manitoba and Saskatchewan. Important habitats for the breeding, moulting and staging of migratory birds are defined. Each area or site is ranked, on the basis of the most current and verifiable biological data, into categories of national, regional, or local importance. Areas and sites are further organized by ecological land units -- ècoregions' and h̀abitat subregions' within a framework of broad geographic ècozones'.

E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

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

Each year shorebirds from North and South America migrate thousands of miles to spend the summer in the Arctic. There they feed in shoreline marshes and estuaries along some of the most productive and pristine coasts anywhere. With so much available food they are able to reproduce almost explosively; and as winter approaches, they retreat south along with their offspring, to return to the Arctic the following spring. This remarkable pattern of movement and activity has been the object of intensive study by an international team of ornithologists who have spent a decade counting, surveying, and observing these shorebirds. In this important synthetic work, they address multiple questions about these migratory bird populations. How many birds occupy Arctic ecosystems each summer? How long do visiting shorebirds linger before heading south? How fecund are these birds? Where exactly do they migrate and where exactly do they return? Are their populations growing or shrinking? The results of this study are crucial for better understanding how environmental policies will influence Arctic habitats as well as the far-ranging winter habitats used by migratory shorebirds.
