With luck
About 10% of wildlife watchers report a Golden Birdwing sighting in Manila on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 51st most-seen of the 122 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Golden Birdwing in Manila on a given day, against under 5% in February and November–December, the lowest months. That is one of Manila's driest months, with about 100 mm of rain against 390 mm in December.
2nd of 2
Of the 2 cities where we can rate Golden Birdwing sightings, Manila ranks 2nd at about 10%. The best odds are in Cebu City (Philippines, about 30%).
Same family: Papilionidae
The closest relatives of the Golden Birdwing that you can see in Manila (family Papilionidae, Swallowtails and Parnassians) are Lime Swallowtail (about 40%), Scarlet Mormon Swallowtail (about 20%) and Philippine Mormon (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden Birdwing is recorded against all the insects logged in Manila (20 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.
