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.

Effects Of Climate Variation On The Breeding Ecology Of Arctic Shorebirds written by Hans Meltofte and has been published by Museum Tusculanum Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2007 with Nature categories.
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.

Shorebirds are the most visible inhabitants of coastal wetlands worldwide. Many undertake spectacularly long flights between their wintering and breeding grounds, embodying the miracle of long-distance migration in a profound way. In this illustrated behavioural ecology the migration, feeding and breeding of these birds are explained in a comprehensive but simple and visually stunning form. The core of the book is based on studies of shorebirds and other waterbirds (such as ducks, geese and gulls) that migrate along the East Atlantic Flyway. The emphasis is on those using the Dutch, German and Danish Wadden Sea; examples from the rest of the world are also included. The authors are experts in the fields of bird migration, shorebird behaviour and intertidal ecology, and have contributed much to our current understanding of these subjects. The 300 magnificent portraits of waterbirds in action were taken by Jan van de Kam, one of The Netherlands' foremost wildlife photographers.

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. Birds of Nunavut is the first complete survey of every species known to occur in the territory. Co-written by a team of eighteen experts, it documents 295 species of birds (of which 145 are known to breed there), presenting a wealth of information on identification, distribution, ecology, behaviour, and conservation. Lavishly illustrated with over 800 colour photographs and 155 maps, this is a visually stunning reference work on the birds that live in and visit Nunavut.

Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This eighth and final volume covers the Malagasy region which comprises Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, the Comoros, Mauritius and Réunion. Every resident and migrant species is covered in full detail, comparable to other volumes in the series, and with a colour map for each species. Vagrants are treated in less detail. All species are illustrated on a beautiful series of 64 colour plates, with original artwork from John Gale and Brian Small. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.
