How many baby Uinta chipmunks are in a litter?
A Uinta chipmunk (Tamias umbrinus) usually gives birth to around 6 babies.
Upon birth, they weight 3 grams (0.01 lbs) and measure 4.2 cm (0′ 2″). They are a member of the Sciuridae family (genus: Tamias). An adult Uinta chipmunk grows up to a size of 12.3 cm (0′ 5″).
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 Uinta chipmunk or hidden forest chipmunk (Neotamias umbrinus), is a species of chipmunk in the family Sciuridae. It is endemic to the United States. Formerly known as Tamias umbrinus, phylogenetic studies have shown it to be sufficiently distinct from the eastern chipmunk as to be placed in a separate genus, Neotamias. The same studies have also suggested that Palmer’s chipmunk may actually be a subspecies of Uinta chipmunk, although the two are still generally regarded as separate species.
