With luck
About 10% of wildlife watchers report a Tailed Jay sighting in Taichung on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 51st most-seen of the 197 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June and August
In those months about 20% of wildlife watchers report a Tailed Jay in Taichung on a given day, against under 5% in February, April and December, the lowest months. Those are among Taichung's wettest months, with about 320 mm of rain a month against 40 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Tailed Jay sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
36th of 45
Of the 45 cities where we can rate Tailed Jay sightings, Taichung ranks 36th at about 10%. The best odds are in Kochi (India, about 40%), Kalyan-Dombivli (India, about 40%) and Mumbai (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Tailed Jay is recorded against all the insects logged in Taichung (21 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.
