European Ground Squirrel near Belmeken Dam (about 1900 meters above sea level) in Eastern Rila Mountains, Bulgaria.
This creature is a world endangered specie, listed in the IUCN Red List. It is threatened because most of its habitats are turned into fields for farming and forests.
Ground squirrels live in colonies of a few hundreds members. A few isolated populations inhabit the mountains of Bulgaria - Rila, Vitosha and Balkan mountains.
