Résumé :
|
Despite the fact that Neusiedlersee is a bird sanctuary of international importance few of the available scientific publications contain data on more than one species or a group of related species. Zimmermann (1943) and Bauer, Freundl & Lugitsch (1955) covered the whole of northern Burgenland in their summarizing articles and were primarily concerned with faunistic aspects, whilst Koenig (1952) was specifically interested in the birds of the reed belt. However, in the last decade a series of more extensive investigations has been devoted to the biology of individual species (Bauer 1965, Leisler 1971, Spitzer 1972 and van den Elzen 1971).
