Nathusius’s Pipistrelle, Pipistrellus nathusii
Nathusius’s pipistrelle (Pipistrellus nathusii) is a species of vesper bat that is native to Europe, with a range that includes western areas like the Caucasus and the Ural Mountains and central and eastern areas, including Britain and Ireland, where it is known to mate. It prefers a habitat within light woodlands or parklands and can typically be found in areas with stable water sources. Like other species of bats, this species migrates to warmer areas in south during the winter.
Nathusius’s pipistrelle reaches and average body length between 1.8 and 2.1 inches, with an average wingspan of up to 9.8 inches and weight of up to .5 ounces. It has slightly long fur that is dark reddish brown at its base and pale at the tip. This species emerges early in the night to hunt for small or medium sized insects, flying quickly at low altitudes.
The breeding season for Nathusius’s pipistrelle occurs between the months of July to September, during which time males gather a number of females to form a harem. These harems or breeding colonies often appear in bat boxes and hollow trees, but they can sometimes be found in buildings. Females will gather in nursery roosts in the spring months to give birth to one or two pups. Nathusius’s pipistrelle appears on the IUCN Red List with a conservation status of “Least Concern.”
