Radio-tracking

Hedgehogs can be fitted with radio transmitters to allow them to be radio tracked. The transmitters are glued onto their spines. The hedgehogs can then be tracked to determine their movements. Radio tracking studies have found that hedgehogs roam an average distance of 1-2km each night and their home ranges, which vary during the year (and between sexes) are on average around 10—20 hectares.
