With luck
About 10% of wildlife watchers report a Contiguous Swift sighting in Singapore on a given day, based on 86 verified sightings from GBIF citizen-science data. It is the 262nd most-seen of the 1045 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.
March, June–September and December–January

GBIF citizen-science records
It is estimated from how often the Contiguous Swift is recorded against all the insects logged in Singapore (86 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.
