It is hard to guess what a Western red-backed vole weights. But we have the answer:
An adult Western red-backed vole (Myodes californicus) on average weights 18 grams (0.04 lbs).
The Western red-backed vole is from the family Cricetidae (genus: Myodes). When reaching adult age, they grow up to 9.8 cm (0′ 4″). On average, Western red-backed voles can have babies 3 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 western red-backed vole (Myodes californicus) is a species of vole in the family Cricetidae. It is found in California and Oregon in the United States and lives mainly in coniferous forest. The body color is chestnut brown, or brown mixed with a considerable quantity of black hair gradually lightening on the sides and grading into a buffy-gray belly, with an indistinct reddish stripe on the back and a bicolored tail about half as long as the head and body.
