Short summary

Effects of an expanding great cormorant colony on small mammals were evaluated. An increase of the number of bird pairs led to decreased δ¹³C and increased δ¹⁵N values in mice hair after the first year of nest appearance. Differences in isotopic signatures were related to species of rodents, pointing to the differences in their diet. Cormorant influence was indirect, the result of biological pollution from guano on rodent foods. Scaring cormorants from the colonies may have the opposite effect.
