    There are remarkable variability in the diet among individuals, but so far we cannot compare them in terms of sex and age data. Diet composition wasinvestigated in a population of a vineyard characterised landscape in Austria. We have analysed stomach contents from road kills in the active season(March-September) of 2016/17. Based on microhystological analysis the percentages of Dicotyledones and Leguminoses were calculated considering seeds in statistical models (generalized least squares, analysis of variance). Seasonally, from June to August/early September high seed percent reducessignificantly the dicot percent in diet. In juveniles males have higher dicot percentages than females while the adults had no sex-difference. Among adults the higher is the seed percentage, the lower is the leguminous percentage. Whole active seasonal calculations for adults have revealed that higher percentage of dicots was earlier in the year; later in the year a significant drop of dicot percentage and an increasing percentage of seeds leads to a significantly smaller percentage of dicotyledones. Moreover, a year effect was found: in 2016 the percentage of dicots was higher than in 2017.
