Sumario:Bio‐logging is an essential tool for the investigation of behavior, ecology, and physiology of wildlife. This burgeoning field enables the improvement of population monitoring and conservation efforts, particularly for small, elusive animals where data collection is difficult. Device attachment usually requires species‐specific solutions to ensure that data loggers exert minimal influence on the animal’s behavior and physiology, and ensure high reliability of data capture. External features or peculiar body shapes often make securing devices difficult for long‐term monitoring, as in the case with small spiny mammals. Here, we present a method that enables high‐resolution, long‐term investigations of European hedgehogs (Erinaceus europaeus) via GPS and acceleration loggers. We collected data from 17 wild hedgehogs with devices attached between 9 and 42 days. Our results showed that hedgehogs behaved naturally; as individuals curled, moved through dense vegetation, slipped under fences and built regular day nests without any indication of impediment. Our novel method makes it possible to not only attach high‐precision devices for substantially longer than previous efforts, but enables detachment and reattachment of devices to the same individual. This makes it possible to quickly respond to unforeseen events and exchange devices, and overcomes the issue of short battery life common to many lightweight loggers.
