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.

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.
Download or read book Flight Identification of Raptors of Europe North Africa and the Middle East written by Dick Forsman and published by Bloomsbury Publishing. This book was released on 2016-02-25 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the ultimate flight-identification guide for the raptors of the Western Palaearctic, covering Europe, North Africa, the Middle East (including Arabia) to Central Asia. Raptors are notoriously hard to identify, even if seen well, and represent perhaps the toughest of all ID challenges for birders. This guide provides identification information for all 60 species that regularly occur in the region, to subspecific level. The text covers every plumage and age in detail, with each species account accompanied by a range of photographs covering all the principal plumages. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces computational data analysis in biology, using the free and popular programming language python 3. The book targets undergraduate and graduate students in biology with an interest in computational techniques, but could also be of interest to students in other scientific disciplines such as biochemistry, environmental sciences and physics. No prior programming experience is required -- this book is intended for the motivated novice! Readers will learn to load and analyze data and produce professional visualizations. The mathematical content is kept to a bare minimum. Examples and exercises are drawn from a wide spectrum across biology, such as epidemiology, ecology, conservation biology, neuroscience, evolution, genetics, genomics and microbiology. Many exercises use realistic datasets published in the scientific literature, such as bacterial genome sequences, animal GPS tracking data, population time series and biodiversity inventories. References to the scientific literature are provided throughout.

Download or read book Fifty Places to Go Birding Before You Die written by Chris Santella and published by ABRAMS. This book was released on 2012-11-16 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: It’s estimated that 50 to 60 million Americans count birding among their hobbies. Some hang feeders in their backyards and accumulate yard lists; others participate in annual “Christmas Counts”; a select few travel to the ends of the earth in an effort to see every bird in the world. With Fifty Places to Go Birding Before You Die, Chris Santella takes the best-selling “Fifty Places” recipe and applies it to this most popular pastime. Santella presents some of the greatest bird-watching venues in the United States and abroad through interviews with prominent birders, from tour leaders and conservationists to ornithologists and academics. Interviewees include ornithologist Kenn Kaufman; David Allen Sibley, author and illustrator of The Sibley Guide to Birds; Rose Ann Rowlett, the “mother of modern birding”; John Fitzpatrick, director of the Cornell Lab of Ornithology; and Steve McCormick, president and CEO of The Nature Conservancy. The places vary from the urban (New York City’s Central Park) to the mystical (the cloud forests of Triunfo in Chiapas, Mexico) to the extremely remote (the sub-Arctic islands of New Zealand). The book includes 40 gorgeous photographs that capture the vibrancy of our feathered friends, and the beautiful places they call home.
