The Pacific jumping mouse (Zapus trinotatus) is a species of rodent in the family Zapodidae. Found in Canada and the United States, its natural habitats are temperate grassland and swamps. Pacific jumping mice can be distinguished from other rodents that belong to the same genus by their larger size. They have a distinct color separation between the back and underside. Other distinctive features of the Pacific jumping mouse, especially in contrast to the Western jumping mouse, include ears fringed with light brown fur or with fur that matches the back.
These rodents prefer to live in moist habitats and are frequently found in riparian or meadow areas near rivulets. They rely on grass seeds as their main diet, and thus they prefer inhabiting areas with thick vegetation, which provide refuge from predators as well as food resources. Besides eating grass, they feed also on fungi and insects. They spend most of the autumn season fattening up in preparation for winter hibernation, which is spent in small burrows in the ground. When their hibernation period of up to 8 months is over, they mate and produce a litter of 4 or more young. Pacific jumping mice have many predators... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pacific Jumping Mouse sighting in Vancouver on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 28 mammals we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pacific Jumping Mouse in Vancouver on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pacific Jumping Mouse sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Vancouver, in our data
Vancouver is the only city on Wallace's Line with enough records to rate Pacific Jumping Mouse sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Rodentia
The closest relatives of the Pacific Jumping Mouse that you can see in Vancouver (order Rodentia, Rodents) are Eastern Gray Squirrel (about 40%), Douglas' Squirrel (about 30%) and American Beaver (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pacific Jumping Mouse is recorded against all the mammals logged in Vancouver (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
