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 Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

Download or read book Tundra Plovers written by Des Thompson and published by Bloomsbury Publishing. This book was released on 2011-11-30 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are four species of tundra plover: the Grey Plover, and the Eurasian, Pacific, and American golden plovers. They breed only in the northern hemisphere, principally on tundra, and migrate far south to coastal mudflats, saltings and agricultural landscapes. They have attracted avid interest from birdwatchers and researchers worldwide, not least the authors who have studied all four species. The Eurasian Golden Plover has a special claim to fame as questions over its flight speed first prompted the compilation of the world bestseller the Guinness Book of Records! This ground-breaking book on shorebirds (waders) examines the taxonomy, appearance, behaviour, ecology and conservation of Golden and Grey plovers, and compares and contrasts their natural history and biogeography. There are detailed accounts on all aspects of their lifestyle including feeding, mating, parental care, moults, migration and avoidance of predators. The personal touches in this book add immensely to its value, not least the authors' first hand experiences of the birds and their haunts. Most of their work presented here has not been published before, adding to the significance of this highly original book. Long-awaited considerations of differences in plumage, vocalisations, habitat use, breeding, movements and food are included. The links between phylogeny, biogeography and behaviour are bound to excite interest. The comparative approach is highly detailed and refreshing, and marks the book as a classic. Ingvar Byrkjedal has also contributed all of the wonderful colour and line illustrations. Over fifty-five photographs, over one hundred and twenty tables and figures, and many other embellishments complete this definitive book.
