Possible
About 20% of wildlife watchers report a Quiller sighting in Calgary on a given day, based on 336 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 25 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December to February
In those months about 40% of wildlife watchers report a Quiller in Calgary on a given day, against about 10% in June to October, the lowest months. Those are among Calgary's driest months, with about 20 mm of rain a month against 120 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Quiller sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.

Same order: Rodentia

GBIF citizen-science records
It is estimated from how often the Quiller is recorded against all the mammals logged in Calgary (336 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.
