Résumé :	In the city of Muenster seven study plots (two in the industrial region, three in the center, and two in the suburbs) were chosen to investigate the winter avifauna. All individuals were registered along routes of 3 km length during 10 visits between October 1995 and March 1996. A total of 17,254 individuals of 44 species were observed. Number of species and population density were higher in the suburbs (garden town) than in the center and the industrial sites of the city. Generally, a few ubiquist species were numerically dominant and had a high probability of being present. The total number of individuals increased up to December and decreased thereafter. However, species showed quite different phenological patterns; some reached maximum numbers in mid winter (e.g. Blackbird), some decreased gradually during winter (e.g. Wren). Ground-dwelling granivorous and omnivorous species represented the most abundant guilds. Insectivorous species were rarer and concentrated in the green parts of the city; they decreased heavily during winter.
