A comprehensive monograph on waders. All of the Nethersole-Thompson family contribute in some measure to this book but it is Dr Desmond Nethersole-Thompson's life-long interest in waders which gives the work its exceptional quality and authority. For well over fifty years the study of waders and their behaviour has been his passion, and his great knowledge and experience are internationally recognised. There is a bonus, too, for the reader in the particular freshness and style of his writing which conveys not only his closely observed, patient study but also the joy and satisfaction he has known in watching such intriguing and beautiful birds, mainly in their Scottish habitats. The core of the book is the comprehensive accounts of the biology and behaviour of 18 species of waders in their breeding haunts. In addition there are chapters on waders generally, wader spacing and dispersion, the wader watchers of past and recent times, and two final chapters on new or returning waders and those pipe-dream species that, not too fancifully, may yet breed one day in these islands. Voice is one of the headings within the species accounts but there is also an appendix of sonagrams of wader songs and calls; there are tables of data and an extensive, selected bibliography. Donald Watson has provided more than a hundred drawings to complement and embellish the text and there are 32 photographs. Jacket paintings are also by Donald Watson.

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.

An authoritative photographic guide on wader identification. Waders are spectacular members of our avifauna. They are especially prevalent along coasts and in wetlands during the spring and autumn migration periods, when members of several species may perform dramatic flocks that wheel and turn in flight. While waders are often particularly striking in summer plumage, identifying these birds outside the breeding season can be problematic for even the most confident of birdwatchers. Waders of Europe is the ultimate guide to wader identification, ecology and biology. Through outstanding photography and concise, detailed text, this book is indispensable for anyone interested in learning more about waders, and is an invaluable tool for identifying birds to species level in the field.

A trans-world journey with an extraorindary shorebird—from Australia's southern ocean to the Arctic and back—that explores the mysteries of the natural world and its power to heal. As the sun lowered and turned Gulf St Vincent fiery, they each called a high-pitched 'peeooowiii!', flashed their black wing-pits, spread their tail skirts and took flight... In a luminous new boook, Andrew Darby follows the odysseys of two seemingly-humble Grey Plovers, little-known migratory shorebirds, as they take previously uncharted ultramarathon flights from the southern coast of Australia to Arctic breeding grounds. On these death-defying flights they dodge predators, typhoons, exhaustion, and countless other dangers before they can breed...and then survive the jrouney all over again and return south to their feeding grounds. But the greatest threat to these, and other long-distance migrants on the flyway, is China's "dragon economy," which is engulfing their vital Yellow Sea staging spots. In Flight Lines, we meet the dedicated people of all nationalities and backgrounds working to save these intrepid birds, from Russia to Alaska, from the rim of the Arctic Sea to the coasts of the Southern Ocean. Out of their hard-won science Darby finds hope for the birds—an unexpected bright light for our times. But his journey to understand these marvellous birds almost ends when he is suddenly diagnosed with an incurable cancer. Then he finds science coming to his rescue too, as his own story and the journey of these little birds intersect in an unexpected and beautiful way.
