Download or read book The Skuas written by Robert W. Furness and published by A&C Black. This book was released on 2010-10-30 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive monograph of the skua. Many birdwatchers may never have seen a skua; those who have will most probably have vivid memories of one or other species flying powerfully past a headland, or twisting and diving in pursuit of its piratical intentions towards a food-laden seabird - or, perhaps more memorably still, of themselves taking evasive action from the power-diving irate skua whose territory they have unwisely invaded. The full classification of the skuas is still debated, but Dr Furness of the Applied Ornithology Unit, Glasgow University, favours six species, of two genera, with five subspecies, based on current knowledge and his own long and dedicated field studies and research. All of the species are treated comparatively under the following chapter titles: Early history and classification, Distributions and populations, Migration patterns, Reversed sexual size dimorphism, Behaviour, Food and feeding, Kleptoparasitism, Plumage polymorphism, Breeding systems and social organisation, Breeding - laying to hatching, Breeding - hatching to fledging, Population dynamics, Pollutants, Skuas and agriculture, Skuas and conservation. The text is supported by 100 maps and diagrams, 30 photographs and 65 tables. In addition, John Busby contributes 35 evocative drawings which more than embellish this erudite and readable summary of an impressive and diverse group of birds. Jacket paintings by John Busby.

Download or read book Skuas and Jaegers written by Klaus Malling Olsen and published by A&C Black. This book was released on 2010-09-30 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first complete identification guide to the skuas of the world. Skuas (and jaegers) are a fascinating and popular group of seabirds that make up a subfamily of just seven species. They can be divided into two main groups: the larger species of Catharacta skuas which are mainly found in the southern hemisphere (with Great Skua breeding in the north), and the three Stercorarius species (also known as jaegers) which breed in the northern hemisphere. Both northern and southern skuas breed at high latitudes and several species are long-distance migrants, performing spectacular migrations through most of the world's oceans, sometimes even flying overland. The individual plumage variation in some species is enormous, creating one of the most puzzling yet fascinating challenges in modern field identification. This guide is designed to enable species identification and correct ageing, and the information presented is based on years of study in the field, detailed examination of photographs and museum skins, and extensive research of the relevant literature. The comprehensive text is accompanied by twelve exquisite colour plates by Hans Larsson, illustrating a wide range of plumages. In addition, there are eight pages of colour photographs and numerous black and white photographs and drawings that show key identification features. With this book, the seabird enthusiast should at last be able to identify almost every skua encountered, whether on a seawatch or at sea.

Download or read book Birds of Aruba Bonaire and Curacao written by Jeffrey V. Wells and published by Cornell University Press. This book was released on 2017-06-15 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds of Aruba, Bonaire, and Curaçao is the essential guide for anyone traveling to those islands. It showcases the more than 280 species seen on Aruba, Bonaire, and Curaçao and provides descriptions of and directions to the best places to bird, from the famous white sand beaches to hidden watering holes to the majestic national parks. Aruba, Bonaire, and Curaçao—the "ABCs"—located in the southwestern Caribbean, not far from Venezuela, share fascinating ecological features with the West Indies as well as the South American mainland, making birding on the islands unique. The identification portion of the book features endemic subspecies such as the Brown-throated Parakeet; a wide variety of wintering North American migrants; spectacular restricted-range northern South American species such as the Yellow-shouldered Parrot, Bare-eyed Pigeon, Troupial, Ruby-topaz Hummingbird, and Yellow Oriole; and West Indian species including the Pearly-eyed Thrasher and Caribbean Elaenia. Colorful introductory sections provide readers with a brief natural history of the islands, detailing the geography, geology, and general ecology of each. In the site guide that follows, Jeffrey V. Wells and Allison Childs Wells share their more than two decades of experience in the region, providing directions to the best birding spots. Clear, easy-to-read maps accompany each site description, along with notes about the species that birders are likely to find. The identification section is arranged in classic field guide format and offers vivid descriptions of each bird, along with tips on how to identify them by sight and sound. The accounts also include current status and seasonality, if relevant, and common names in English, Dutch, and Papiamento, often inspired by the unique voices of the birds, such as the "chibichibi" (Bananaquit) and "choco" (Burrowing Owl). The accompanying color plates feature the beautiful work of illustrator Robert Dean. The final section, on conservation, raises awareness about threats facing the birds and the habitats on which they rely and summarizes conservation initiatives and needs, offering recommendations for each island.

Download or read book RSPB Seabirds written by Marianne Taylor and published by Bloomsbury Publishing. This book was released on 2016-07-28 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A lavish celebration of the seabirds of the British Isles. Seabirds are the living links between land, air and sea. They enjoy a freedom that even humans, with all our technological assistance, can barely imagine. Many species travel mind-boggling distances across the length and breadth of our planet before returning to land to breed in large, deafening and confusingly crowded colonies. Yet within this commotion each mated pair forms a bond of extreme closeness and tenderness that survives separation each winter and may persist for decades. The long and geologically varied coastline of the British Isles provides homes for internationally important numbers of breeding seabirds. Visiting their colonies is always unforgettable, whether they are cliff-faces packed with Guillemots, islands white-capped by clustered Gannets on their nests, flat beaches crowded with screaming Arctic Terns or seaside rooftops overlaid with a second townscape of nesting gulls. The changing fortunes of these seabird cities reveal to us the health of the vast, unseen but incredibly rich marine world that surrounds us. RSPB Seabirds showcases some of our most exciting and enigmatic bird species as vital and living components of one of our greatest natural assets: our coastline. The author presents detailed biographies of all the seabird species that breed in and around the British Isles, and also looks at the many species that breed elsewhere but which, regularly or occasionally, visit British waters. Every page of this sumptuous book features beautiful photographs of wild seabirds engaged in their daily work of hunting, travelling, protecting themselves and their territories, courting and raising a family.

Available in PDF, EPUB and Kindle. Book excerpt: The Atlas plots the results of the survey organised by the BTO and the IWC during the years 1968-72. Over 250 maps show the distribution of 218 species. This companion volume to The Atlas of Wintering Birds in Britain and Ireland is derived from yearly surveys of breeding birds in Britain and Ireland during 1968-72, organised by the British Trust for Ornithology and the Irish Wildbird Conservancy. Each of the 3,862 10-km squares of Britain and Ireland was visited during the five years and the resulting records (over 285,000) are summarised in the maps. The full-page maps plot the known distribution of all but 11 of the 229 breeding species located during the survey period. Each map has an accompanying text which describes the species' habitat, the problems involved in proving breeding, the historical background to the species' range and any changes in its numbers. The probable reasons for these changes are discussed and an attempt made to assess the total number of birds for each species. Jacket design by Robert Gillmor.
