The diet of the Red-backed Shrike (Lanius collurio) was analysed from collars in nestlings, pellets and prey remains in larders. All the material was collected from the same territories in western Poland.A total of 2855 prey items were identified from all the samples. Insects, mainly Coleoptera, Hymenoptera and Orthoptera, constituted 98.9% of all the prey items identified.In order to determine the diet and predict the impact of food resources on Red-backed Shrike populations, three methods should be used together: pellet content analyses, collar sampling and larder analysis. Our findings suggest that pellet content analysis is an easy and non-invasive method for estimating prey diversity and the frequency index. However, collars are necessary to determine nestling diets. Analyses of prey remains in larders should be used to find large prey, handled before consumption. In a more advanced geographical analysis of the content of the shrike diet, we suggest pooling the data obtained by different methods from the same place, and/or carefully assign methods of diet analyses.
