Book Description
"/i/Arctic Shorebirds in North America//i/ represents a study that is one of the remarkable achievements of wildlife fieldcraft, like those done by Aldo Leopold in the 1930s and by the Craighead Brothers in the 1960s. To conduct a study of this scientific caliber in the great expanse and harsh climate of the Arctic makes it one of the great wildlife investigations whose value will only grow with time."--Larry Niles, Conserve Wildlife Foundation of New Jersey "It is most timely that Jonathan Bart and Victoria Johnston have gathered information on shorebirds that breed in the Arctic regions of North America. Data on these birds is generated at a wide range of locations by many different individuals and teams, and this book puts it into perspective. It is particularly valuable to have this treatise when so many shorebird species worldwide are in marked decline."--Clive Minton, Australasian Wader Studies Group "When the PRISM program for pan-Arctic shorebird monitoring was introduced, everyone agreed with its laudable aims, but it seemed impractical. How could shorebird biologists with limited time and resources acquire robust data on the size and trend of shorebird populations across the American Arctic? Now, the credibility gap has been bridged. /i/Arctic Shorebirds in North America//i/ presents the rigorous, practical methods that will be the foundation of Arctic shorebird monitoring for years to come. I look forward to Arctic PRISM becoming the keystone of shorebird conservation in the Western Hemisphere."--Humphrey Sitters, editor of /i/Wader Study Group Bulletin//i/

Book Description
A lavishly illustrated, large-format reference book by two preeminent experts on North American shorebirds More than half a century has passed since the publication of The Shorebirds of North America, Peter Matthiessen’s masterful natural history of what is arguably the world’s most amazing and specialized bird group. In the intervening decades, our knowledge about these birds has grown significantly, as have the threats to their populations and habitats. Pete Dunne and Kevin Karlson celebrate Matthiessen’s classic book with this updated and expanded natural history of North American shorebirds. This elegantly written book begins by introducing readers to the unrivaled splendor of shorebirds and goes on to cover topics ranging from their biology and habitats to courtship and breeding, flight, the perils of migration, and conservation. Detailed accounts convey the richness and variety of the five family groups, with incisive, fact-filled descriptions of all 52 species of shorebirds known to breed in North America. Featuring hundreds of breathtaking images by Karlson and other photographers and drawing on the latest science, The Shorebirds of North America is a worthy tribute to Matthiessen’s enduring work and an indispensable reference for bird lovers everywhere.

Book Description
The volumes in the Birds of Ontario series summarize life history requirements of bird species that are normally part of the ecology of Ontario. This is the second volume in the series and completes the treatment of the nonpasserine bird species occurring in Ontario on a regular basis. Information on habitat, limiting factors, and status is summarized for 83 species in this volume. These topics are covered for the three primary avian seasons: breeding, migration, and winter. Habitat, nest sites, territoriality, site fidelity, annual reproductive effort, habitat loss and degradation, environmental contaminants, and a variety of other topics are covered in the species accounts. Maps depicting breeding and wintering range are presented for most species along with drawings by Ross James. Birds of Ontario is an essential reference source for wildlife biologists, environmental consultants, and planners preparing or reviewing environmental impact statements and environmental assessments. Serious birders will find the volumes of interest as well. Although the books focus on Ontario birds, the information is highly relevant to adjacent provinces and states.

Book Description
Shorebirds are model organisms for illustrating the principles of ecology and excellent subjects for research. Their mating systems are as diverse as any avian group, their migrations push the limits of endurance, and their foraging is easily studied in the open habitats of estuaries and freshwater wetlands. This comprehensive text explores the ecology, conservation, and management of these fascinating birds. Beginning chapters examine phylogenetic relationships between shorebirds and other birds, and cover shorebird morphology, anatomy, and physiology. A section on breeding biology looks in detail at their reproductive biology. Because shorebirds spend much of their time away from breeding areas, a substantial section on non-breeding biology covers migration, foraging ecology, and social behavior. The text also covers shorebird demography, population size, and management issues related to habitat, predators, and human disturbances. Throughout, it emphasizes applying scientific knowledge to the conservation of shorebird populations, many of which are unfortunately in decline.
