Résumé :	Cormorants Phalacrocorax carbo sinensis are regularly counted at their roost Pleidelsheimer Baggersee 20 km north of Stuttgart/SW-Germany at least three times per month. There is a continuing steady increase in numbers in contradiction to the numbers of Cormorants overwintering in Baden-Wurttemberg. The pattern of the seasonal occurrence shows peaks in midwinter or in spring. The seasonal dynamic varies extremely between typical patterns of overwintering waterfowl and typical migration patterns with peaks in autumn and spring. A maximum of Cormorants in November as it is typical for the latest development in nearly every other area could not be shown in the study area. Some aspects of the daily routine, feeding grounds and dynamics between different roost sites are given.
