Litter Size

How many babies does a Columbian ground squirrel have at once? (litter size)

How many baby Columbian ground squirrels are in a litter?

A Columbian ground squirrel (Spermophilus columbianus) usually gives birth to around 3 babies.With 1 litters per year, that sums up to a yearly offspring of 3 babies.

Each of those little ones spend around 24 days as a fetus before they are released into the wild. Upon birth, they weight 9 grams (0.02 lbs) and measure 5.6 cm (0′ 3″). They are a member of the Sciuridae family (genus: Spermophilus). An adult Columbian ground squirrel grows up to a size of 29.6 cm (1′ 0″).

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 average litter size of a Columbian ground squirrel is 3

The Columbian ground squirrel (Urocitellus columbianus) is a species of rodent common in certain regions of Canada and the northwestern United States. It is the second largest member of the genus Urocitellus, which is part of the tribe Marmotini, along with marmots, chipmunks, prairie dogs, and other holarctic ground squirrels. They are stout, with short dense fur, which is characteristically tawny across the bridge of the nose. Social encounters often are initiated with kissing behavior and the most common activity above ground is standing at attention. Residing in mountainous terrain and high plains in northern latitudes, they hibernate most of the year in burrows, which may be used for many years. They are emaciated when emerging in the spring. These long periods of torpor earned the squirrels the moniker “Seven Sleepers”, since the rests last around seven months. The Columbian ground squirrel came to the attention of the scientific community through writings produced by Lewis and Clark, while 21st century molecular genetics has more finely illuminated its ties with other close relatives.
