European hedgehogs (Erinaceus europaeus) live in New Zealand’s high alpine zones, but it is not known if populations persist in such areas year-round. We hypothesised that hedgehogs respond to the arrival of winter conditions (cold temperatures, snowfall, and lack of available food) by making short-distance altitudinal migrations to lower elevations. We tested this by capturing and fitting GPS/VHF backpacks to six adult female hedgehogs at elevations between 1500 and 1800 m, and by following their movements throughout the austral summer to winter period (January to June) 2020.
