The Soprano pipistrelle (Pipistrellus pygmaeus) has been recently recognized, based on its acoustic and genetic characteristics. It is a sibling species of the widely distributed Common pipistrelle (P. pipistrellus). P. pygmaeus was found in many European countries, including Switzerland. A MSc project shed new light on the distribution of these two cryptic species and their ecological niche differentiation in Switzerland. The Soprano pipistrelle was found to be much rarer than its sibling species, preferring lowland river ecosystems near richly structured landscapes and urban areas. Due to its scarcity the Soprano pipistrelle is a potentially endangered species in Switzerland.
