Rare
Under 5% of wildlife watchers report a Rounded Palm-Redeye sighting in Singapore on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 891st most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rounded Palm-Redeye in Singapore on a given day, so our monthly data shows no clear season.
6th of 6
Of the 6 cities where we can rate Rounded Palm-Redeye sightings, Singapore ranks 6th at under 5%. The best odds are in Tuen Mun (China, about 10%), Bengaluru (India, about 10%) and Kochi (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Rounded Palm-Redeye is recorded against all the insects logged in Singapore (6 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.
