Myotis aurascens

Whiskered bat
Whiskered bat

Limited distribution range – from the Bulgarian Danube plain through eastern Romania and Ukraine up to the Caucasus. There are single records from Turkey and the Peloponnese, Greece. The Balkan Whiskered bat may possibly belong to the Steppe Whiskered bat, in which case the distribution would range from the Balkans to northern Italy.1

The Steppe Whiskered bat is similar to the Balkan Whiskered bat. The muzzle of the Steppe Whiskered bat is shorter and the tip of the ears are narrower than those of the Whiskered bat; the outer edge of the ear also appears to be more strongly convexly curved. Genetic methods are needed for clear separation between the two species.

Echolocation calls start between 105 – 112 kHz and end at 37 – 43 kHz.

Floodplain landscapes and steppe-like open land areas. In Caucasus also in mountain steppes up to more than 2000 m.

In rock crevices and constructions joints of bridges.

Mixed nursery colonies with Balkan Whiskered bats. In the beginning of June the females are pregnant. Births take place from the middle to the end of June.

The threats are not clear, except roost loss.
