Book Description
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.

Book Description
The gyr is the largest, fastest and arguably the most beautiful falcon in the world. For centuries man has been driven to acquire live specimens from their Arctic territory for sport and even as currency. This is a study of the species, using drawings, sketches, paintings and photographs. The author examines the gyrfalcon's role in natural history, its place in literature and its long-established use in falconry.

Book Description
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.

Biology of the Peregrine and Gyrfalcon in Greenland

Author: William A. Burnham
Publisher: Museum Tusculanum Press
ISBN: 9788763511629
Category : Science
Languages : en
Pages : 32

Book Description
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.

Book Description
Applied Raptor Ecology provides raptor researchers with the blueprint to determine which questions should be asked, record consistent data usable by researchers worldwide, apply appropriate analysis of those data, and break down the obstacles to collaboration. Editors Dr. David Anderson and Dr. Christopher McClure of The Peregrine Fund and Dr. Alastair Franke of the Arctic Raptors Project recruited 13 raptor ecology experts from around the world to contribute chapters ranging in scope from terminology to systematic data management to home range estimation: examples of estimator effects. Anderson states, "This book is designed to be almost like a cookbook to enable readers to collect data in a standardized, well-organized manner and run analyses based on the questions they want to answer. The gyrfalcon is the species we chose as a case study to illustrate raptor biology techniques, but these methods and questions can be applied to almost any raptor species around the world."Applied Raptor Ecology is a valuable addition to the bookshelf of every biologist, whether in the field for many years or as an entry level graduate planning a thesis project. Additional features of this book include:* a companion website for users to download computer code to perform analyses in R that are adaptable to individual research needs and questions* a photographic and morphometric guide to aging Gyrfalcon nestlings* guidelines for conducting a camera study of nesting raptors

But when her favorite rescued falcon, Stark, hurts Karma, her parents insist that they return the bird to its previous owner--in Canada. On the way to bring Stark back, a car accident in the middle of nowhere leaves Karma's dad trapped, and it's up to Karma to find a way to rescue him and her younger brother. When Karma loses her way trying to get help, she crosses paths with Cooper, a troubled teenaged boy.

The Falcon Thief

Category : True Crime
Languages : en
Pages : 336

Book Description
A “well-written, engaging detective story” (Kirkus Reviews, starred review) about a rogue who trades in rare birds and their eggs—and the wildlife detective determined to stop him. On May 3, 2010, an Irish national named Jeffrey Lendrum was apprehended at Britain’s Birmingham International Airport with a suspicious parcel strapped to his stomach. Inside were fourteen rare peregrine falcon eggs snatched from a remote cliffside in Wales. So begins a “vivid tale of obsession and international derring-do” (Publishers Weekly), following the parallel lives of a globe-trotting smuggler who spent two decades capturing endangered raptors worth millions of dollars as race champions—and Detective Andy McWilliam of the United Kingdom’s National Wildlife Crime Unit, who’s hell bent on protecting the world’s birds of prey. “Masterfully constructed” (The New York Times) and “entertaining and illuminating” (The Washington Post), The Falcon Thief will whisk you away from the volcanoes of Patagonia to Zimbabwe’s Matobo National Park, and from the frigid tundra near the Arctic Circle to luxurious aviaries in the deserts of Dubai, all in pursuit of a man who is reckless, arrogant, and gripped by a destructive compulsion to make the most beautiful creatures in nature his own. It’s a story that’s part true-crime narrative, part epic adventure—and wholly unputdownable until the very last page.
