Badger Meles meles diet: a review of literature from the former Soviet Union

We review 69 studies of the diet of Badgers Meles meles L. in the former Soviet Union, using information from 58 Russian-language papers. Animal foods occurred more frequently in the diet than vegetal foods and constituted, on average, 62% of all intake by volume. The most important individual food categories were insects (30% by volume) and small mammals (20% by volume), which appear to be staple foods of Badgers over virtually the whole of the former Soviet Union. Earthworms were mentioned in only a few reports and never exceeded 5% of the diet by volume. Other animal foods included birds, reptiles, amphibians, fish, molluscs and carrion. Fruits were seasonally important in some areas while roots, tubers, bulbs, cereals and nuts were also eaten; but in general, the Soviet literature lacks detailed information about vegetal foods. Many authors comment on seasonal variation in the diet and there was statistically significant seasonal variation in the frequency with which small mammals, reptiles, insects and vegetal foods were eaten. No largescale geographical trends were apparent in the composition of the diet, but foods which were of minor importance overall, such as reptiles, amphibians and molluscs, were sometimes eaten with high frequency in particular localities. The results support the view that Badgers are opportunistic, generalist foragers, with a preference for animal foods when these are available.
