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.

This book was released on 1993 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Each spring during migration, thousands of birds stop temporarily in offshore open-water areas of the Beaufort Sea to feed, rest, and court. Some proposed sites for offshore oil exploration and development are in the vicinity of possible key staging areas. The potential for oil spills in these areas is one of the most serious threats to birds in the western Arctic. Information on the distribution of birds during spring migration provides the basis for evaluating threats"--Executive summary.

Book excerpt: "Each spring during migration, hundreds of thousands of birds stop temporarily in offshore areas of the Beaufort Sea to feed, rest, and court. In 1992 and 1993, the Northern Oil and Gas Action Program provided funding to study spring waterbird distributions in relation to oil development. The objectives of this study were to: to examine spring waterbird distributions in offshore areas of the Beaufort Sea, Amundsen Gulf, and Lambert Channel; and to assess the potential threats from oil exploration and development to spring migrants in the southern Beaufort Sea. We flew aerial surveys for birds in May and June, 1992 and 1993. This report presents results from 1993"--Executive summary, p. i.
