In Sweden, the month of May is when bears in the country wake up after their winter hibernation period and leave their dens. It is also the time to change the batteries in their “mobile phones”. In the forests between Orsa and Sveg in the Dalarna region, some 50 bears come out of hibernation wearing a mobile terminal around their necks. A number of bears in the Orsa area have been equipped with a mobile terminal over the past two years. These terminals on the bears can automatically send SMS messages to a research station, as well as receive them, after which positioning technology is used to keep track of the bears’ movements.
