With luck
About 10% of wildlife watchers report a Large Tabby sighting in Seattle on a given day, based on 103 verified sightings from GBIF citizen-science data. It is the 66th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Large Tabby in Seattle on a given day, against under 5% in August to May, the lowest months. That is one of Seattle's driest months, with about 20 mm of rain against 190 mm in November.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Large Tabby sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 29 cities where we can rate Large Tabby sightings, Seattle ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Helsinki (Finland, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Tabby is recorded against all the insects logged in Seattle (103 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.
