It is hard to guess what a Collared pika weights. But we have the answer:
An adult Collared pika (Ochotona collaris) on average weights 129 grams (0.28 lbs).
The Collared pika is from the family Ochotonidae (genus: Ochotona). They can live for up to 6 years. When reaching adult age, they grow up to 18.8 cm (0′ 8″). On average, Collared pikas can have babies 2 times per year with a litter size of 3.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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.
