American red squirrel size: How big do they get?

How big does a American red squirrel get? Here is an overview over the average adult age:

A grown American red squirrel (Tamiasciurus hudsonicus) reaches an average size of 18.8 cm (0′ 8″).

When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 12 years, they grow from 6 grams (0.01 lbs) to 200 grams (0.44 lbs). Talking about reproduction, American red squirrels have 4 babies about 1 times per year. The American red squirrel (genus: Tamiasciurus) is a member of the family Sciuridae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a American red squirrel is (0' 8

The American red squirrel (Tamiasciurus hudsonicus) is one of three species of tree squirrels currently classified in the genus Tamiasciurus, known as the pine squirrels (the others are the Douglas squirrel, T. douglasii, and Mearns’s squirrel, T. mearnsi). The American red squirrel is variously known as the pine squirrel, North American red squirrel and chickaree. It is also referred to as Hudson’s Bay squirrel, as in John James Audubon’s work The Viviparous Quadrupeds of North America (hence the species name). The squirrel is a small, 200–250 g (7.1–8.8 oz), diurnal mammal that defends a year-round exclusive territory. It feeds primarily on the seeds of conifer cones, and is widely distributed across North America wherever conifers are common, except on the Pacific coast, where its cousin, the Douglas squirrel, is found instead. The American red squirrel is not found on most of the Great Plains or in the southeastern United States, as conifer trees are not common in those areas. The squirrel has been expanding its range into hardwood forests.
