This book was released on 1984 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A ten year study began in 1972 in West Greenland to investigate the breeding biology of the peregrine falcon. Data on nesting gyrfalcons were also collected. Thirty-four peregrine nesting sites were examined in the 6050 km2 inland study area near Søndre Strømfjord. Limited research also centered in Disko Bugt and Frederikshåb. Peregrines were found nesting predominantly on high, south-facing cliffs, which overlooked large areas. The mean minimum distance between peregrine eyries was 7.7 km for the inland area (1972 and 1973) and 55 km for the coast (1974). Approximately 60 percent of the inland nesting sites were occupied each year. A ten-year average production of 1.90 young per occupied site and 2.78 young per successful site was determined. Lapland longspurs, snow buntings, wheatears, and redpolls comprised 90 percent of the peregrines diet. Raven nests and prey availability may be the most significant factor affecting falcon density. Addled peregrine eggs, eggshell fragments, and peregrine prey species were collected. Whole eggs averaged 14.3 ppm wet weight (305 ppm lipid weight ) DDE, while eggshell measurements showed a 16 percent thinning compared with pre-1940 eggs from Greenland. Prey species carried low levels of DDE. The peregrine population appears to be at a near critical contamination level, and a small increase in DDE level could contribute to a population decline. No indication of a decline has been observed during the study, and the population appears stable. The project banded 185 peregrines, from which 8 recoveries occurred. The recoveries suggest peregrines migrate south to winter in South America.

Download or read book The History and Range Expansion of Peregrine Falcons in the Thule Area Northwest Greenland written by Andrew G. Gosler and published by Museum Tusculanum Press. This book was released on 2012-07-01 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the discovery and history of the most northern breeding population of Peregrine Falcons in the world, near Thule Air Base in northwest Greenland (75.9–77.6° N). Although the region was explored by scientific expeditions as early as 1818, Peregrines were not documented in the area until the 1930s. By the early 1990s the population had become well established, with a warming climate enabling Peregrines from further south to expand their breeding range northward. Here Burnham and his co-authors present their comprehensive findings on the biology and ecology of this population based on thirteen years of research from 1993 to 2005.
Download or read book The Gyrfalcon written by Eugene Potapov and published by A&C Black. This book was released on 2010-01-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: WINNER OF THE WILDLIFE SOCIETY'S 'BEST SCIENCE BOOK 2006' AWARD This book is the first monograph on one of the most beautiful and admired birds in the world. The Gyrfalcon is the world's largest and most powerful falcon - a truly awe-inspiring bird which inhabits the ferociously inhospitable Arctic taiga, from Greenland and Iceland right across Siberia and northern Canada. Its plumage varies from a dark mottled grey to pure white - the white birds in particular are coveted by birders and falconers. Like other titles in the series, it covers all aspects of the species' biology, taxonomy, distribution, status and historical associations with mankind. The result is an exhaustively researched and enthrallingly readable biography of a spectacular bird, illustrated throughout with photographs and line drawings.
Download or read book Adventure Tourism written by David Huddart and published by Springer Nature. This book was released on 2019-10-25 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents a comprehensive overview of the environmental impacts of various types of adventure tourism and how these can be best managed. This volume follows on from the authors previous textbook – ‘Outdoor Recreation: Environmental Impacts and Management’ and continues the aim of developing a deeper understanding of how tourist numbers impact the environment and to provide practical solutions to these problems. Combining their own first-hand experience and research with extensive literature review the authors' present several popular adventure tourism destinations from across the globe, including the Arctic, the Himalayas, Africa, Australia and Scotland as case studies. Chapters cover the particular challenges faced by each region: including impacts on animals and birds; the spread of invasive plant species and diseases; trail impacts on vegetation; impacts on geological, historical and archaeological sites and pollution and waste issues. A discussion and evaluation of the possible management actions for minimising these impacts and how outdoor recreation tourists can be regulated concludes each chapter. This practical and engaging textbook will be invaluable to students and scholars of adventure tourism and outdoor recreation as well as practitioners and managers working in the field.

Book excerpt: Taphonomic studies are a major methodological advance, the effects of which have been felt throughout archaeology. Zooarchaeologists and archaeobotanists were the first to realise how vital it was to study the entire process of how food enters the archaeological record, and taphonomy brought to a close the era when the study of animal bones and plant remains from archaeological sites were regarded mainly as environmental indicators.This volume is indicative of recent developments in taphonomic studies: hugely diverse research areas are being explored, many of which would have been totally unforeseeable only a quarter of a century ago.

Book excerpt: Gyrfalcons and humans have shared a remarkable relationship since prehistoric times. These extraordinary arctic falcons have been revered, coveted as an item of commerce, persecuted, and enjoyed as a spectacle of sport for at least ten thousand years. Today, climate change has brought new challenges, with habitat in the far north changing rapidly as natural cycles begin to break down. Drawn from over thirty years of study and observation, this in-depth study provides a comprehensive view of the gyrfalcon’s place in the arctic ecosystem, including their inextricable link to their primary pray, the ptarmigan, and their antagonistic relationship with golden eagles. It explores the connection the bird has had with humanity in both legend and practice, and the challenges it faces as its habitat continues to change. This definitive look at the gyrfalcon shows us both sides of the majestic bird: the master of its domain and a threatened species facing an uncertain future.
Download or read book Behavioural Ecology of Western Palearctic Falcons written by Giovanni Leonardi and published by Springer Nature. This book was released on 2020-12-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with “The Lanner falcon” published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species.
