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
Nunavut is a land of islands, encompassing some of the most remote places on Earth. It is also home to some of the world’s most fascinating bird species. The windswept tundra, rocky shorelines, and icy waters of this thinly populated land are integral to the survival of numerous breeding and non-breeding birds, including the colourful King Eider, the stately Snowy Owl, the spritely Snow Bunting, and the globe-spanning Northern Wheatear. Birds of Nunavut is the first complete survey of every species known to occur in the territory. It is co-written by a team of eighteen experts who have conducted a combined total of 300 seasons of fieldwork in Nunavut. They document 295 species of birds (of which 145 are known to breed in the territory), presenting a wealth of information on identification, distribution, ecology, behaviour, and conservation. Lavishly illustrated with over 800 colour photographs and 155 maps, it is a visually stunning reference work on the birds that live in and visit Nunavut.

Book Description
About 50 species of shorebirds breed in the Arctic, where they constitute the most characteristic component of the tundra avifauna. Here, we review the impact of weather and climate on the breeding cycle of shorebirds based on extensive studies conducted across the Arctic. Conditions for breeding shorebirds are highly variable among species, sites and regions, both within and between continents. Weather effects on breeding are most moderate in the Low Arctic of northern Europe and most extreme in the Siberian High Arctic. The decision of whether or not to breed upon arrival on the breeding grounds, the timing of egg-laying and the chick-growth period are most affected by annual variation in weather. In large parts of the Arctic, clutch initiation dates are highly correlated with snowmelt dates and in regions and years where extensive snowmelt occurs before or soon after the arrival of shorebirds, the decision to breed and on the breeding ecology of clutch initiation dates appear to be a function of food availability for laying females. Once incubation is initiated, adult shorebirds appear fairly resilient to variations in temperature with nest abandonment primarily occurring in case of severe weather with new snow covering the ground. Feeding conditions for chicks, a factor highly influenced by weather, affects juvenile production in most regions. Predation has a very strong impact on breeding productivity throughout the Arctic and subarctic, with lemming Dicrostonyx spp. and Lemmus spp. fluctuations strongly influencing predation rates, particularly in the Siberian Arctic. The fate of Arctic shorebirds under projected future climate scenarios is uncertain, but High Arctic species and populations appear particularly at risk. Climatic amelioration may benefit Arctic shorebirds in the short term by increasing both survival and productivity, whereas in the long term habitat changes both on the breeding grounds and on the temperate and tropical non-breeding areas may put them under considerable pressure and may bring some of them near to extinction. Their relatively low genetic diversity, which is thought to be a consequence of survival through past climatically-driven population bottlenecks, may also put them more at risk to anthropogenic-induced climate variation than other avian taxa.

Book Description
The finest, most lavishly illustrated photographic guide to the birds of eastern North America Combining informative and accessible text, up-to-date maps, and—above all—stunning color photographs, this is the best and most lavishly illustrated photographic guide to the birds of eastern North America. All of the images have been carefully selected to convey both the sheer beauty and the key identification features of each bird, and many of the photos are larger than those found in other guides. Wherever possible, a variety of plumages are pictured, providing visual coverage and usefulness matching any artwork-illustrated field guide. And many of the images are state-of-the-art digital photographs by Brian Small, one of North America's finest bird photographers. These pictures, many seen here for the first time, reproduce a previously unimaginable level of detail. Finally, the ranges of nearly all species are shown on maps from the Cornell Laboratory of Ornithology, the authority on North American birding. New and experienced birders alike will find this guide indispensable: the clear layout will help novices easily identify the birds they see, while the superb photographs will help seasoned birders confirm identifications. The best, most lavishly illustrated photographic guide to the region's birds Larger color photos than most other field guides Fresh contemporary design—clear, easy-to-use, and attractive Informative, accessible, and authoritative text Range maps from the Cornell Laboratory of Ornithology Covers entire eastern half of mainland North America and the arctic and subarctic territorial islands of the U.S. and Canada

Book Description
Shorebirds of North Americacontains over 200 color photos of all the breeding and commonly occurring shorebird species found in North America. Species accounts show breeding and nonbreeding plumages when differences occur, as well as many immature and juvenile plumages. Some similar species are shown side by side to allow for easier ID comparison, such as the dowitchers, yellowlegs and willets.

Book Description
Thousands of ravenous tiny shorebirds race along the water’s edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego. Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the loss of horseshoe crabs—ancient animals that come ashore but once a year—threatens not only the survival of red knots but also human well-being: the unparalleled ability of horseshoe-crab blood to detect harmful bacteria in vaccines, medical devices, and intravenous drugs safeguards human health. Cramer offers unique insight into how, on an increasingly fragile and congested shore, the lives of red knots, horseshoe crabs, and humans are intertwined. She eloquently portrays the tenacity of small birds and the courage of many people who, bird by bird and beach by beach, keep red knots flying.
