Possible
About 20% of wildlife watchers report a Tailed Jay sighting in Cuc Phuong National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 82nd most-seen of the 126 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Tailed Jay is recorded against all the insects logged in Cuc Phuong National Park (10 verified sightings from 2019 to 2026), 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.
