The Food of the White-tailed Sea Eagle (Haliaeetus albicilla) at Lake Baikal, East Siberia

A long-term study (1991-2001) of the food of White-tailed Sea Eagles in the Svâtoj Nos wetlands at Lake Baikal, Northeastern Russia, revealed that these eagles feed predominantly on water birds, mainly ducks. Anecdotal data from the Selenga Delta in Southeastern Lake Baikal indicate that White-tailed Sea Eagles generally prefer birds as their prey in the Lake Baikal area.

Abstract

The new zoological exposition of the National Museum will be installed in eight exhibition halls on the second floor of the Historical Building. The exposition has the preliminary title Evolution and thematically, it will follow several significant evolutionary events, which enabled animals to occupy Earth. The first two exhibition halls will be devoted to invertebrates and their ability to occupy all kinds of environments. The following two exhibition halls will introduce fish-like vertebrates, amphibians, and reptiles and they will focus on the most important evolutionary step of vertebrates – stepping out of the water and onto land. The next hall will be devoted to the origin of flight and birds’ conquering of the skies. The last two halls will be dedicated to mammals and their origins and conquering of land, water, and air. The visitor will become acquainted with contemporary organisms as the results of a long evolutionary process. The exhibitions will be based on authentic collection items to the maximum possible extent, though models and multimedia will also be used on several occasions. The exposition should also include the restoration of the popular Pokoutník Gallery.
