It is hard to guess what a American pika weights. But we have the answer:
An adult American pika (Ochotona princeps) on average weights 158 grams (0.35 lbs).
The American pika is from the family Ochotonidae (genus: Ochotona). It is usually born with about 11 grams (0.02 lbs). They can live for up to 7 years. When reaching adult age, they grow up to 19 cm (0′ 8″). On average, American pikas can have babies 2 times per year with a litter size of 2.
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 American pika (Ochotona princeps), a diurnal species of pika, is found in the mountains of western North America, usually in boulder fields at or above the tree line. They are herbivorous, smaller relatives of rabbits and hares.
