Daubenton's bat (Myotis daubentonii), is a Eurasian bat with quite short ears. It ranges from Britain to Japan (Hokkaido) and is considered to be increasing its numbers in many areas.
Daubenton's bat is found throughout Ireland and Europe, and as far as Japan and Korea. The bat is mostly found in woodlands and always chooses roosts close to water sources such as rivers or canals.
Summer colonies are formed in underground caves, tunnels, cellars, mines, and underneath bridges. These colonies are also always near water. Daubenton's bat hibernates in the same type of locations from September to late March or April.
