The Mediterranean horseshoe bat (Rhinolophus euryale) is a species of insectivorous bat in the family Rhinolophidae. It is found in the Mediterranean region and Balkan peninsula, as well as parts of Italy. The head and body are normally between 43 and 58 millimetres (1.7 and 2.3 in), with a 22–30 millimetres (0.87–1.18 in) tail. The wingspan of R. euryale is between 30 and 32 centimetres (12 and 13 in), with a standard weight between 8 and 17.5 grams (0.28 and 0.62 oz). The upper connecting process is pointed and slightly bent downwards, and is distinctly longer than the lower connecting process, which is broadly rounded when seen from below.
The fur is fluffy, with a light grey base. The dorsal side is grey-brown, with sometimes a slight reddish tinge, while the ventral side is grey-white or yellow-white. There is little known information about the Mediterranean horseshoe bat's reproductive cycle. Nurseries normally hold between 50 and 400 females, with males sometimes present. The colonies in the summer and winter are very large and they are surrounded by small satellite colonies. The main colonies are in caves and can include... Wikipedia →

Rare
Under 5% of wildlife watchers report a Mediterranean horseshoe bat sighting in Pyrénées National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 30 mammals we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January–February and October
In those months about 10% of wildlife watchers report a Mediterranean horseshoe bat in Pyrénées National Park on a given day, against under 5% in March–September and November–December, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Mediterranean horseshoe bat sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Mediterranean horseshoe bat sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Rhinolophus
The closest relatives of the Mediterranean horseshoe bat that you can see in Pyrénées National Park (genus Rhinolophus, Horseshoe Bats) are Lesser Horseshoe Bat (about 10%) and Greater Horseshoe Bat (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mediterranean horseshoe bat is recorded against all the mammals logged in Pyrénées National Park (6 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.
