Discussion The diet and feeding habits of martens living in the examined villages and farms showed similarity in the summer-autumn period. There was not such a definite habitat dependent difference as it was found in other studies (e.g. in Denmark, urban and rural areas: Rasmussen and Madsen 1985; in Switzerland, urban and rural habitats: Tester 1986; in France, farmland and marshes: Lódé 1994; in Hungary, village and agricultural environments: Lanszki 2003). Relying on the overall diet independent of habitat types, cultivated fruits dominated which means unlimited food sources in locations of this study. Fruits are important sources of vitamin and carbohydrate, their consumption is generally high (or primarily) in the summer-autumn period (e.g. Holisová and Obrtel 1982, Tester 1986, Genovesi et al. 1996, Martinom and Preatoni 1995, Lódé 1996, Lanszki et al. 1999, Prigioni et al. 2008). Seeds are defecated without digest by martens and because they have large home ranges (in villages: 10-88 ha, Herrmann 1994; 66 ha, Seiler et al. 1994; and in farm environments: 350-400 ha, Serafini and Lovari 1993; 185-300 ha, Herrmann 1994) they have an important role in spreading seeds. However, in the villages primarily small birds, in farms small mammals were the most important animal foods, but from a taxonomic viewpoint was not a significant habitattype dependent difference in the diet of the martens. Similarly to the present study, bird consumption was more typical in feeding of those martens which live near settlements (Rasmussen and Madsen 1985, Tóth 1998, Lanszki 2003, Heltai et al. 2005). Although in most of cases a species level identification can not be given, consuming of birds primarily being unbeneficial in viewpoint of nature conservation. It also makes problem that martens often choose such hiding places where bats or bam owls also find shelter (Tóth et al. 2007). Distribution differences made by marten scat and bam owl pellet
