It is hard to guess what a Northern Idaho ground squirrel weights. But we have the answer:
An adult Northern Idaho ground squirrel (Spermophilus brunneus) on average weights 300 grams (0.66 lbs).
The Northern Idaho ground squirrel is from the family Sciuridae (genus: Spermophilus). When reaching adult age, they grow up to 18.1 cm (0′ 8″). On average, Northern Idaho ground squirrels can have babies 1 times per year with a litter size of 7.
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 northern Idaho ground squirrel (Urocitellus brunneus) is a species of the largest genus of ground squirrels. This species and the Southern Idaho ground squirrel were previously considered conspecific, together called the Idaho ground squirrel.
