Daubenton's bat or Daubenton's myotis (Myotis daubentonii) is a Eurasian bat with rather short ears. It occurs across Eurasia, from Ireland in the west to Hokkaido in the east, and is believed to be increasing its numbers in many areas of its range.
This bat was first described in 1817 by Heinrich Kuhl, who named it in honour of French naturalist Louis-Jean-Marie Daubenton. Daubenton's bat is a medium-sized to small species. The bat's fluffy fur is brownish-grey on the back and silvery-grey on the underside. Juveniles have darker fur than adults. The bats have reddish-pink faces and noses, but the area around the eyes is bare. When the bat is agitated, the ears are held at right angles. The wings and tail membrane are dark brown.
Daubenton's bat is typically 45 to 55 mm long, with an average wingspan of 240 to 275 mm, and weighs between 7 and 15 g. Daubenton's bats can live for up to 22 years. In Lieto, Finland a male called Nestori that lives in an old water mill has been tracked since 2008 and was approximately 21 years old in 2024. Daubenton's bat is found throughout Ireland and Europe, and as far as Japan and Korea. The bat is mostly... Wikipedia →

With luck
About 10% of wildlife watchers report a Daubenton's bat sighting in Cévennes National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 30 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June and September–November
In those months about 20% of wildlife watchers report a Daubenton's bat in Cévennes National Park on a given day, against under 5% in July and December–April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Daubenton's bat sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Daubenton's bat sightings, Cévennes National Park has the highest daily chance: about 10%. Next come Pyrénées National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Daubenton's bat is recorded against all the mammals logged in Cévennes National Park (16 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
