Résumé :	Since 1950 706 data sets of 3456 birds were recorded. The Goldeneye is a regular migrant and winter visitor. It was recorded in all winters since 1959. Nevertheless actual overwintering is not evident. Oversummering is unknown, too, although records exist for all months. The daily maximum amounts to 88 individuals. Greater ponds were clearly preferred. Monthly numbers are subject to strong fluctuations. They increase in November, culminate in March and decrease rapidly in April. The number of drakes is higher only in January and February contrary to other results in Bavaria.
