[4] The European free-tailed bat roosts by day in crevices in cliffs, in rocky gorges, under overhangs, in holes in tall buildings, under roof tiles or under stone bridges.

It emerges at dusk and flies at a great height with a swift direct flight, not exhibiting the sudden twists and turns shown by many other bat species.

The gestation period is about eighty days and a single youngster is born in some dark, concealed location.

[4] The European free-tailed bat is included by the IUCN in its Red List of Threatened Species as being of "Least Concern".

The population trend is not known but it is a common species in suitable habitats and bats in general receive protection in a number of European Union member states.
