The Balkan chamois Rupicapra rupicapra balcanica Bolkay, 1925 has a highly fragmented distribution in the mountainous regions of the Balkan Range, including Bulgaria. In 2021, the Balkan chamois was recorded in two locations outside its known distribution range, i.e., in the natural park “Sinite Kamani”, eastern Stara Planina Mts. This is the first hard evidence of the presence of the species in the Eastern Stara Planina Mts. Two new records of Balkan chamois were documented in two different parts of the nature park in the second half of 2025. In the second record, it was observed among a herd of stray grazing domestic goats.
