Distribution and habitat selection of the Common Scoter Melanitta nigra in the eastern German North Sea

Understanding the processes affecting the distribution of an avian (and every other) species in time and space necessitates the inclusion of a variety of factors. Choice and utilisation of a habitat should be seen in the context of energetic costs and benefits, as organisms are believed to distribut...
