Marking quilled animals for individual recognition may be challenging. This is particularly true for European hedgehogs Erinaceus europaeus, whose defense mechanism involves the concealment of muzzle and underparts. Heat-shrink tubes have been widely used to mark quills, but they do not adapt to the morphological structure of the spines and are rapidly lost, thus reducing method effectiveness. We adapted a cheap and ethical method used to mark crested porcupine quills, which involves the use of colored adhesive tapes applied to quills. The retention period of this marking technique lasts up to 9 months, allowing short-term field studies and possibly dispersal distances measurements. The method could be improved by doubling the number of marked spines and by reapplying adhesive tape at every recapture event. Moreover, the use of a marking code can be obtained by subdividing the body of the hedgehog into six body areas, to increase the number of marking possibilities, through the combination of tape colors and body areas.

Various hypotheses have been proposed in order to explain self-anointing in hedgehogs, but until now its function is still poorly understood. In order to obtain a better understanding of self-anointing, we investigated whether this behaviour is gender, age and seasonal dependent in seven European hedgehogErinaceus europaeus Linnaeus, 1758 populations. Signs of self-anointing were observed in more than 11% of all observations. First-year independent young were found to self-anoint more than adults, while male hedgehogs bore more signs of self-anointing than females. Self-anointing in adults displayed a peak in summertime, while no clear pattern was observed for young. We conclude that self-anointing is clearly dependent on gender, age and season.

Ten radio-tagged hedgehogs Erinaceus europaeus (Linnaeus, 1758) were monitored during the winter of 2001/2002 in a Danish rural area. The study was aimed at measuring parameters essential for hibernation success and the fate of the mainly juvenile hedgehogs being recorded. The average duration of hibernation was found to be 179 days for juveniles (n = 6) and 198 days for adult females (n = 3). The most often used nesting habitat types were forested areas (55%). The hedgehogs typically used 2 nests during the hibernation period, but up to 4 different nests used by one hedgehog were found. Time spent in different nests varied considerably (6-187 days). The average weight loss during hibernation was 22.1% for juveniles and 30.2% for adult females. Minimum body mass sufficient for survival was registered to be 513 g prior to hibernation. Nine of the hedgehogs survived until departure from their hibernacula, while the fate of 1 juvenile is unknown. Indication was thus found that the minimum weight required to survive the winter has previously been overestimated.
