Abstract

During a detailed study of the Grey Wagtail Motacilla cinerea in western Sweden, several cases of polygamy were observed. Social polygyny, one male mating with two females, was confirmed in three cases, and was strongly suspected in a fourth case. In the three confirmed cases the distance between the two nests was 3, 15, and 100 m. One case of social polyandry was also suspected, since one female was observed with alarm behaviour together with two males in June.
