What is the maximal age a Collared pika reaches?
An adult Collared pika (Ochotona collaris) usually gets as old as 6 years.
When born, they weight 8 grams (0.02 lbs) and measure 5.1 cm (0′ 3″). As a member of the Ochotonidae family (genus: Ochotona), a Collared pika caries out around 3 little ones per pregnancy, which happens around 2 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 collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S.), and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no other recognized subspecies. It is asocial, does not hibernate, and spends a large part of its time in the summer collecting vegetation that is stored under rocks (“haypiles”) as a supply of food for the winter. Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. Thousands of trips are made during July and August to collect vegetation for winter.
