With luck
About 10% of wildlife watchers report a Tailed Jay sighting in Guangzhou on a given day, based on 81 verified sightings from GBIF citizen-science data. It is the 25th most-seen of the 482 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.
July and October
In those months about 20% of wildlife watchers report a Tailed Jay in Guangzhou on a given day, against under 5% in January, the lowest month.
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.
38th of 45
Of the 45 cities where we can rate Tailed Jay sightings, Guangzhou ranks 38th at about 10%. The best odds are in Kochi (India, about 40%), Kalyan-Dombivli (India, about 40%) and Mumbai (India, about 40%).
Same genus: Graphium
The closest relatives of the Tailed Jay that you can see in Guangzhou (genus Graphium, Swordtails, Jays, Bluebottles and allies) are Common Bluebottle (about 10%) and Common Jay (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tailed Jay is recorded against all the insects logged in Guangzhou (81 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.
