摘要

This article describes interaction between three carnivore species: raccoon dog's (Nyctereutes procyonoides), European badger's (Meles meles) and red fox'es (Vulpes vulpes) in Poland. Diets of the three predators studied in Bialowieza Forest shows similarity but also differences in main food items. The red fox was the most and raccoon dog the last carnivorous of these three predators. In the Bialowieza Forest red fox feed more small mammals, whereas European badger specialised in earthworms. Raccoon dog consumed mainly carcass, amphibians and reptiles. The food niches of raccoon dog and European badger overlapped more than the red fox and other species. Additionally, the three predatory mammals have different habitat niche breadth, which is closely correlated with their foraging strategies. Despite of that these 3 carnivore's species share many resources, and on the same area.
