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.

This book was released on 1986 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report serves as a source manual of raptors occurring on Army Corps of Engineers lands in the Pacific Northwest. It consists primarily of a comprehensive literature review covering aspects of the biology of 35 species of eagles, hawks, falcons, vultures, and owls. The manual was developed to provide biologists and resource managers with background information to facilitate the application of sound raptor management practices on project lands. While the literature is cosmopolitan, references are applicable to species found in, but not limited to, the Pacific Northwest. Approximately 4,000 citations, compiled through 1983, are included. General guidelines on raptor management and survey techniques are provided. An outline of techniques is given for habitat assessment, development, and management applicable to Federal lands, and recommendations are provided for management needs regarding various land use practices and recreational activities. Basic procedures for conducting raptor nesting surveys, migration counts, and winter surveys are outlined. Raptor studies conducted on project lands in the US Army Engineer Division, North Pacific, are summarized.

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.

Download or read book Biology of the Peregrine and Gyrfalcon in Greenland written by William A. Burnham and published by Museum Tusculanum Press. 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.
