About 10% of wildlife watchers report a Rounded Palm-Redeye sighting in Taipei on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 261st most-seen of the 765 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April, June–August and October–December

GBIF citizen-science records
It is estimated from how often the Rounded Palm-Redeye is recorded against all the insects logged in Taipei (36 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.
