The tiny Nathusius’ pipistrelle, weighing only 6–10 grams, travels almost 2,000 km from its breeding grounds
in north-eastern Europe to its main hibernation areas in south-west Europe. Populations in Russia are thought
to winter in the eastern Caucasus and the Volga Delta. Recently, the breeding range of Nathusius’ pipistrelle has
expanded towards the west and the south. New nursery colonies have been found in Ireland, the Netherlands,
France, and Germany. Only females return to their breeding areas. After their first migration, males usually stay in
mating roosts along migration routes or in hibernation areas, and in riverine forests and marshlands. Nathusius’
Pipistrelles may also regularly cross the North Sea as many bats have been found on oilrigs. Nathusius’ pipistrelle
is protected under the Agreement on the Conservation of Populations of European Bats (EUROBATS).
