How many baby Insular voles are in a litter?

A Insular vole (Microtus abbreviatus) usually gives birth to around 3 babies.

Each of those little ones spend around 21 days as a fetus before they are released into the wild. Upon birth, they weight 3 grams (0.01 lbs) and measure 1.8 cm (0′ 1″). They are a member of the Muridae family (genus: Microtus). An adult Insular vole grows up to a size of 16 cm (0′ 7″).

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 insular vole or St. Matthew Island vole (Microtus abbreviatus) is a species of rodent in the family Cricetidae. It occurs only on St. Matthew Island and the adjacent Hall Island, in Alaska. On these Bering Sea islands, insular voles live in damp lowland areas, on the lower slopes of mountains, and on rye grass-covered beaches. They are diurnal and eat plant matter. Birds and Arctic foxes (which are the only other mammals on the island) prey on the voles.
