We investigated food preferences of three species of dormice, testing consumption by captive animals. One type of food was provided to an animal and its "suitability" scored for each species, according to whether it was or was not consumed. If it was eaten, the time when it was consumed was recorded (after 24, 48 or 72 hours). In total, 17 types of animal food and 46 of plant food were tested. Animal foods offered included different arthropods, eggs, snails and chicken meat. Plant food consisted of fruits, seeds, nuts and green parts. Glis glis consumed -24% of animal material offered and 100% of plant food types, Dryomys nitedula consumed - 77% of animal and 54% of plant food types. Graphiurus murinus consumed - 94% of animal and 63% of plant food types. G. glis showed a significantly higher preference for plant foods rather than animal material, and preferred plant food much more than the other two species. Both D. nitedula and G. murinus preferred animal more than plant food and and did not differ in preferences and diversity of both kinds of food they consumed. Thus, G. glis can be considered as principally a herbivore, while D. nitedula and G. murinus are rather meat-eaters. It can be concluded that food niches, especially of the two European dormice, are separate and thus in natural conditions they do not compete strongly for food resources.
