What is the maximal age a American red squirrel reaches?
An adult American red squirrel (Tamiasciurus hudsonicus) usually gets as old as 12 years.
American red squirrels are around 34 days in the womb of their mother. When born, they weight 6 grams (0.01 lbs) and measure 4.2 cm (0′ 2″). As a member of the Sciuridae family (genus: Tamiasciurus), a American red squirrel caries out around 4 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 18.8 cm (0′ 8″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
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.
