| Résumé : | From the calcareous marshes near Chelm (SE Poland) 14 cases of Marsh Harriers robbing prey from Honey Buzzards are reported. Six times the victims lost Hymenoptera (Apoidea) nests to a Marsh Harrier. These kleptoparasitic attacks benefit from three main factors: 1. Open habitats, e.g. meadows and marshes, 2. Large prey that can be identified from a distance, 3. High nutritional value of the prey. |
