Myotis brandtii
Introduction
Brandt’s bat is very similar to the whiskered bat and was only recognised as a separate species in 1970. Both are small species with somewhat shaggy fur – the Brandt’s bat is slightly larger than the whiskered bat. The two species are most reliably differentiated through dentition and penis shape. Other distinguishing features are thought to include tragus shape and claw length. Brandt’s bats emerge soon after sunset and feed through the night at low heights in woodland and near water.
