Abstract

On the agricultural landscape (346 ha) in northeastern Slovenia (46°25'N, 15°45'E) the Magpie Pica pica was studied during the winter period (December–February) 1997/98. The average density was 8.38 individuals/km2. The Magpies foraged mainly single or in pairs. Differences in flock size between months were significant only on arable land (Kruskal-Wallis test, Chi-square = 7.98, df = 2, P < 0.05) but not in urban areas.
