The circadian and monthly activity rhythms of dormice Glis glis (Linnaeus, 1766) and their foraging for a preferred food source (hazels) have been studied. Dormice showed a monophasic pattern of activity from June to early November. The daily active period started from or after sunset, and ended usually before sunrise. In June and September, however, the foraging was prolonged ca 1 hr after sunrise. This suggests that the active phase is limited by the endogenous cycle of dormouse rather than by photoperiod. Hazelnut intake began in June before the fruits were ripened, and went on until the supply was exhausted, in August.
