Environmental group Kallisto has caught and tagged six bears in northern Greece to study their habits as part of research being conducted for the construction of the Egnatia Highway. The study relates to the construction of the 37- kilometer Panagia-Grevena stretch that runs through forest area home to brown bears, researchers said. The animals have been tagged with tiny radio transmitters that can be monitored via satellite and will give researchers information on how bears will be affected by the construction of one of Greece’s largest infrastructure projects. Kallisto researchers have given names to the bears, such as «Four Fingers» and «The General» based on their physical characteristics. The study is being funded from the highway’s budget, in which provision has been made for environmental protection.
