The subject of the study is the behaviour of Mallard’s Anas platyrhynchos and was carried out in the city of Szczecin (Poland) in 2009–2010. We compared frequency of fights, rapes, courtships, copulations and whistles on a water basins within both big and small flocks, and in different phenology periods. The study shows significant relationship between season, number of ducks on a pond and frequency of fights, as well as between whistles and fights, whistles and season and courtships and season. The results show that the most active period for ducks are the autumn and winter months (pairing period), while more aggressive behaviours can be observed when the population density is high.
