The foraging behavior of Reed Warbler (Acrocephalus scirpaceus), Sedge Warbler (A. schoenobaenus) and Marsh Warbler (A. palustris) was surveyed on three crop types (spring cereals, winter cereals, and oil seed rape) in western Poland. The foraging intensity was greatest in oil seed rape, while the lowest was in spring cereals. For Sedge Warbler, oil seed rape fields were visited mainly in May, while cereal fields were visited in June and July. The number of foraging visits decreased with increasing distance from a breeding marsh patch. There was no difference in distance traveled to different crop types. There was a significant negative correlation between marsh patch area and foraging intensity for all species combined. This study shows that oil seed rape may be useful as a foraging habitats for some farmland birds during the breeding season.
