In 3 days ~30% in a week ~60%
Graphium doson, the common jay, is a black, tropical papilionid (swallowtail) butterfly with pale blue semi-transparent central wing bands that are formed by large spots. There is a marginal series of smaller spots. The underside of wings is brown with markings similar to upperside but whitish in colour. The sexes look alike. The species was first described by father and son entomologists Cajetan and Rudolf Felder.
It is widespread and common throughout Southeast Asia, including lower elevations in Sri Lanka and southern India, Eastern Ghats, Satpuras, Bengal, Assam and Bangladesh, and the Himalayan foothills. The species is however scarce in southern Honshū, Japan. Wikipedia →

With luck
About 10% of wildlife watchers report a Common Jay sighting in Taipei on a given day, based on 156 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 765 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–July and October
In those months about 20% of wildlife watchers report a Common Jay in Taipei on a given day, against under 5% in November to February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common 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.
31st of 41
Of the 41 cities where we can rate Common Jay sightings, Taipei ranks 31st at about 10%. The best odds are in Solapur (India, about 50%), Durg (India, about 40%) and Vijayawada (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Common Jay is recorded against all the insects logged in Taipei (156 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.
