Common Pipistrelle Pipistrellus pipistrellus

Britain’s smallest and most abundant bat, familiar from its fast, jerky flight along hedgerows and around garden trees at dusk. Very small; dark reddish-brown fur; uniformly dark brown face, ears and wing membranes; echolocates at around 45 kHz, distinguishing it from the Soprano pipistrelle. Roosts in small gaps in buildings and often forms large summer maternity colonies. Image: © Jakob Fahr, iNaturalist.
