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.

Download or read book Peregrine Falcon written by James H. Enderson and published by University of Texas Press. This book was released on 2013-08-26 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: A superb success as a bird, combining great speed, aeronautical grace, and fearlessness...inhabitant of wild places, inaccessible cliffs, and skyscrapers...worldwide dweller, trans-equatorial migrant, and docile captive—the peregrine falcon stands alone among all others of its kind. Perhaps this is why so many varied people rushed to its aid when it faced decimation by pesticide poisoning. In this personal and highly entertaining memoir, Jim Enderson tells stories of a lifetime spent studying, training, breeding, and simply enjoying peregrine falcons. He recalls how his boyhood interest in raptors grew into an ornithological career in which he became one of the leading experts who helped identity DDT as the cause of the peregrine falcon's sudden and massive decline across the United States. His stories reveal both the dedication that he and fellow researchers brought to the task of studying and restoring the peregrine and the hair-raising adventures that sometimes befell them along the way. Enderson also seamlessly weaves in the biology and natural history of the peregrine, as well as anecdotes about its traditional and widespread use in falconry as an aggressive yet tractable hunter, to offer a broad portrait of this splendid and intriguing falcon.

Book excerpt: Depletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes.

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 Peregrine Falcon written by Derek Ratcliffe and published by A&C Black. This book was released on 2010-06-30 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of The Peregrine Falcon was widely recognised as a classic of its kind, documenting not only the species' biology but also the sad tale of its decline due to the impact of pesticides. This extensively revised and enlarged second edition takes full account of important new developments in the story of this bird during the intervening 12 years. It reports one of the few notable successes in wildlife conservation: the full restoration of British and Irish Peregrine populations, and their appreciable recovery in other countries where numbers had also been greatly reduced by the impact of organochlorine pesticides. The pattern of increase in Britain has been extremely varied, from districts where numbers are now far higher than at any time in recorded history, to others where the bird is now at its lowest ebb. The examination of the reasons for these differences helps us to understand the most recent developments in the Peregrine saga. Particular attention has been paid to the recent major advances in our knowledge of Peregrine biology, such as its movements, population turnover, food and nesting habits. Many of the tables and figures have been revised and brought up to date so that this volume, like its predecessor, is once again by far the most detailed and readable reference on this most evocative of birds. Donald Watson's colour paintings, monochrome washes and line drawings, and the original photographs, illustrate the book as before. Cover illustration by Donald Watson.
