Rare
Under 5% of wildlife watchers report an Extra-spot Swift sighting in Singapore on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 960th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Extra-spot Swift in Singapore on a given day, so our monthly data shows no clear season.
3rd of 3
Of the 3 cities where we can rate Extra-spot Swift sightings, Singapore ranks 3rd at under 5%. The best odds are in Tuen Mun (China, about 10%) and Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Extra-spot Swift is recorded against all the insects logged in Singapore (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.
