The results of the study indicated food supply to be important for both predator species during the winter period, although the role of biotic factors in site selection in the autumn could not be clearly demonstrated. The winter distribution of the two species could, however, be explained well in terms of abiotic factors. It is suggested that these and other similar predator species have well-defined overwintering requirements and that these can be exploited in the management of field boundary habitats.
