This book was released on 1973 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents results and discusses the adequacy of a forecast system developed for predicting the density of bird migration near Canadian Forces Base Cold Lake in Alberta. The system was developed for use in reducing the number of collisions between birds and aircraft. Migration forecasts were based on known migration density patterns, known correlations between weather and migration density, and the local weather forecast. During spring and fall 1970, routine forecasts of hourly densities of night-time migration were presented at pilot briefings for night flying, and the forecasts were subsequently checked against actual densities obtained from time-lapse films and surveillance radar. Prediction accuracies are given for both spring and fall seasons and their degree of accuracy for military flight planning is noted.

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 1992 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1981 to 1984, Whooping Cranes Grus americana migrating between their summer range in and near Wood Buffalo National Park in Canada and their winter range on and near the Aransas National Wildlife Refuge in the United States were studied by means of radiotelemetry. Objectives of the aerial study included a precise determination of migration routes, duration of occupancy and location of stopover sites, and documentation of migrating crane behavior and mortality.
