It is hard to guess what a Water vole (North America) weights. But we have the answer:
An adult Water vole (North America) (Microtus richardsoni) on average weights 92 grams (0.2 lbs).
The Water vole (North America) is from the family Muridae (genus: Microtus). It is usually born with about 5 grams (0.01 lbs). They can live for up to 0.75 years. When reaching adult age, they grow up to 15.4 cm (0′ 7″). On average, Water vole (North America)s can have babies 2 times per year with a litter size of 5.
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 water vole (Microtus richardsoni) is the largest North American vole. It is found in the northwestern United States and southern parts of western Canada. This animal has been historically considered a member of genus Arvicola, but molecular evidence demonstrates that it is more closely related to North American Microtus species. Water voles are on the USDA Forest Service Region 2 sensitive species list because they maintain very small populations and there is high concern that their required habitat may be declining.These animals have gray-brown or red-brown fur with gray under parts. Their large hind feet help make them excellent swimmers, and they are found in alpine or semi-alpine meadows near water. They feed on grasses, leaves, roots and seeds, also eating small invertebrates. Water voles dig burrows that are connected to water sources, and are considered a semi-aquatic species.They are active year-round, tunneling through snow during the winter. Their burrows often have entrances at the water’s edge or under water, and they usually live in colonies of 8-40 individuals along the waterway.
