How many baby Eurasian harvest mouses are in a litter?

A Eurasian harvest mouse (Micromys minutus) usually gives birth to around 5 babies.With 2 litters per year, that sums up to a yearly offspring of 10 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 4.3 cm (0′ 2″). They are a member of the Muridae family (genus: Micromys). An adult Eurasian harvest mouse grows up to a size of 5.9 cm (0′ 3″).

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.

It is typically found in fields of cereal crops, such as wheat and oats, in reed beds and in other tall ground vegetation, such as long grass and hedgerows. It has reddish-brown fur with white underparts and a naked, highly prehensile tail, which it uses for climbing. It is the smallest European rodent; an adult may weigh as little as 4 grams (0.14 oz). It eats chiefly seeds and insects, but also nectar and fruit. Breeding nests are spherical constructions carefully woven from grass and attached to stems well above the ground.
