About 30% of wildlife watchers report a Golden Birdwing sighting in Cebu City on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 12 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 Golden Birdwing is recorded against all the insects logged in Cebu City (5 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.
