About Myotis daubentonii (Kuhl, 1817)
Daubenton's bat (Myotis daubentonii) is a small to medium-sized bat species. It has fluffy fur that is brownish-grey on the back and silvery-grey on the underside; juveniles have darker fur than adult individuals. This species has reddish-pink faces and noses, with bare skin around the eyes. When agitated, Daubenton's bats hold their ears at right angles. Their wings and tail membrane are dark brown. Adults of this species typically reach a body length of 45 to 55 mm, have an average wingspan between 240 and 275 mm, and weigh 7 to 15 g. Daubenton's bat ranges across Ireland, Europe, and extends as far east as Japan and Korea. It mainly inhabits woodlands, and usually selects roosts located close to water sources such as rivers or canals. Summer colonies form in caves, tunnels, cellars, mines, and under bridges, and all of these colony sites are positioned near water. Daubenton's bat hibernates in these same types of locations between September and late March or April.
