Abstract

At lake Attersee (Upper Austria) waterbird census data (January) from 27 years were set in relation to local limnological and meteorological conditions and to the middle European trend of waterbird populations. Preliminary results obtained by applying multiple regression analysis show a relationship of local abundance related to global trend numbers at least in the case of the Tufted Duck (Aythva fit ligula) whereas Pochard (Aythya ferina) numbers of lake Attersee show a possible link to local temperature situations. More data about feeding habitats are needed for explaining the fluctuations of wintering waterbird numbers on wintering sites.
