Hedgehog activity was observed under experimental conditions. The daily and seasonal activity of White-Breasted hedgehogs Erinaceus roumanicus was recorded using a camera trap in 2024-2025. Individuals were pre-captured at the edge of a forest near Saransk. It was found that the highest activity was recorded in June (36,5%), the lowest in December (0,6%). In January-March the hedgehogs were asleep. In June and October, hedgehogs were active around the clock. Hedgehog activity was recorded throughout the year in a temperature range from -17°C to +29°C. The frequency of activity recordings was significantly lower during daylight hours than during darkness in spring (Z = -3,18; p < 0,01), summer (Z = -4,61; p < 0,01), and autumn (Z = -3,58; p < 0,01). The beginning and end of continuous twilight-nocturnal activity of hedgehogs in Mordovia coincide with the times of sunset and sunrise, respectively, which indicates the influence of photoperiod on the seasonal variability of hedgehog activity. The highest activity was observed from 21:00 to 23:00 h. The least activity of hedgehogs was observed from 14:00 to 15:00 h and from 05:00 to 07:00 h.
