Rare
Under 5% of wildlife watchers report a Large Tabby sighting in Chicago on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 538th most-seen of the 978 insects 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 Large Tabby in Chicago on a given day, so our monthly data shows no clear season.
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.
28th of 29
Of the 29 cities where we can rate Large Tabby sightings, Chicago ranks 28th at under 5%. The best odds are in Helsinki (Finland, about 10%), Seattle (United States, about 10%) and Vienna (Austria, about 10%).
GBIF citizen-science records
It is estimated from how often the Large Tabby is recorded against all the insects logged in Chicago (13 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.
