The southern birch mouse (Sicista subtilis) is a species of birch mouse in the family Dipodidae. It is found on the Balkan Peninsula, Ukraine, Romania, southern Russia and one isolated location in Hungary in the Borsodi Mezőség Protected Landscape Area. The Hungarian subspecies (S. subtilis trizona) is critically endangered and strictly protected. The first living specimen was captured after a 70-year-long hiatus in 2006.
The most prominent characteristic of the southern birch mouse is the dark stripe down the center of the back, which is bordered by two narrow bright stripes on both sides. From head to rump it measures from 56 to 72 mm, with a tail from 110 to 130% of the main body length. The background fur color is gray-brown.
The southern birch mouse is pronouncedly a steppe dweller. It makes a subterranean burrow in the summer and hibernates. It eats green plants and insects.
