It is hard to guess what a Northwestern deer mouse weights. But we have the answer:
An adult Northwestern deer mouse (Peromyscus sitkensis) on average weights 28 grams (0.06 lbs).
The Northwestern deer mouse is from the family Muridae (genus: Peromyscus). When reaching adult age, they grow up to 9.9 cm (0′ 4″). On average, Northwestern deer mouses 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 northwestern deer mouse or Keen’s mouse (Peromyscus keeni) is a species of rodent in the family Cricetidae. It is found in British Columbia in Canada and in Alaska and Washington in the United States. It was named after the Rev. John Henry Keen in 1894.According to the study from “Spatial Variation in Population Dynamics of Sitka Mice in Floodplain Forests” which was published by Thomas A. Hanley and Jeffrey C. Barnard, the sitka mouse or Northwestern deer mouse has an interesting perspective regarding the floodplain and habitat. The article has done an experiment testing the relationship between floodplain habitat and has concluded that the floodplain forset does not necessarily makes a favorable habitat for sitka mouse.
