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 Current Ornithology written by Richard Johnston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 5 of this series continues its coverage of currently active re search fields in ornithology. Because an editor can never be a disin terested observer of his or her own editorial efforts, any claim for su periority of this volume is not without conflict of interest. Even so, Volume 5 has certain merits that even a parent should acknowledge, and I find the current chapters not merely timely and authoritative but compelling in their demand for a reader's attention. Wolfgang and Roswitha Wiltschko provide a perceptive review of magnetic orientation in birds, a piece dedicated to Fritz Merkel, the pioneer in studies of magnetic orientation. Sergei Kharitonov and Doug las Siegel-Causey are concerned with the behavioral ecology of seabird coloniality, emphasizing their field experiences in the USSR and the United States. Ted Miller examines the application of studies of bird behavior to comparative biology, pursuing the interface of behavior and evolutionary biology adumbrated by Konrad Lorenz in the 1930s. Jeremy Raynor gives us a summary of the work over the past decade on bird flight, which is not, by turns, as complex or as simple as we had formerly believed. Carrol Henderson describes recent develop ments in nongame bird conservation, based on his pioneering work in the State of Minnesota. Alan Kamil discusses optimal experimental design for research in ornithology, a field in which experimental work is frequently difficult to pursue.
