How many baby Creeping voles are in a litter?
A Creeping vole (Microtus oregoni) usually gives birth to around 3 babies.With 4 litters per year, that sums up to a yearly offspring of 12 babies.
Each of those little ones spend around 23 days as a fetus before they are released into the wild. Upon birth, they weight 1 grams (0 lbs) and measure 3.2 cm (0′ 2″). They are a member of the Muridae family (genus: Microtus). An adult Creeping vole grows up to a size of 9.9 cm (0′ 4″).
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 creeping vole (Microtus oregoni), sometimes known as the Oregon meadow mouse, is a small rodent in the family Cricetidae. Ranging across the Pacific Northwest of North America, it is found in forests, grasslands, woodlands, and chaparral environments. The small-tailed, furry, brownish-gray mammal was first described in the scientific literature in 1839, from a specimen collected near the mouth of the Columbia River. The smallest vole in its range, it weighs around 19 g (0.67 oz). At birth, they weigh 1.6 g (0.056 oz), are naked, pink, unable to open their eyes, and the ear flaps completely cover the ear openings. Although not always common throughout their range, there are no major concerns for their survival as a species.
