Radio-tracking
Radio transmitters can track hedgehogs when they are glued onto their spines.
Researchers do this to determine their movements.
Radio tracking studies have found that hedgehogs roam an average distance of 1-2km each night. Their home ranges vary during the year, and between sexes. On average, they are around 10—20 hectares.
Radio-tracking is an important tool for learning about hedgehogs.
