The feeding ecology of the stone marten in a rural area of Central Italy was assessed by faecal analysis. Habitat analysis, performed through a Geographical Information System, and intensive radio‐tracking allowed us to investigate intra‐population variations of diet in relation to habitat. The species’feeding habits were opportunistic: fruit and berries were the staple diet but mammals and birds were also important. Diet varied seasonally in relation to resource availability, with a predominance of fruit in autumn and frequent presence of insects in summer. Individuals living in adjacent areas but in different habitats (wooded and rural) showed significant variations of diet, adapting their feeding habits to local availability of foods. The great adaptability of the stone marten to very different resource conditions can represent a key to the species’success through its wide range.
