A contribution to the knowledge of the trophic spectrum of the Common toad (Bufo bufo L., 1758) (Amphibia: Anura) from Bulgaria

During our study we identified 500 prey items in 20 prey categories in the trophic spectrum of Bufo bufo with average number of prey items per stomach 25.00. The most important prey taxon is Formicidae (70.20%), followed by Coleoptera (especially Carabidae – 11.40%), as well as non-insect invertebrates (Isopoda, Gastropoda, Arachnida) which also play significant role. The estimated trophic niche breadth is low – 1.96.
