How many baby Common pipistrelles are in a litter?
A Common pipistrelle (Pipistrellus pipistrellus) usually gives birth to around 1 babies.With 1 litters per year, that sums up to a yearly offspring of 1 babies.
Each of those little ones spend around 44 days as a fetus before they are released into the wild. Upon birth, they weight 1 grams (0 lbs) and measure 2 cm (0′ 1″). They are a member of the Vespertilionidae family (genus: Pipistrellus). An adult Common pipistrelle grows up to a size of 3.9 cm (0′ 2″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The common pipistrelle (Pipistrellus pipistrellus) is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, southwestern Asia, and may extend into Korea. It is one of the most common bat species in the British Isles. In Europe, the northernmost confirmed records are from southern Finland near 60°N. In 1999, the common pipistrelle was split into two species on the basis of different-frequency echolocation calls. The common pipistrelle uses a call of 45 kHz, while the soprano pipistrelle echolocates at 55 kHz. Since the two species were distinguished, a number of other differences, in appearance, habitat and food, have also been discovered.
