Rare
Under 5% of wildlife watchers report a Common Straight Swift sighting in Taipei on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 498th most-seen of the 765 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.
September and October
In those months about 10% of wildlife watchers report a Common Straight Swift in Taipei on a given day, against under 5% in November to August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Common Straight Swift sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
19th of 19
Of the 19 cities where we can rate Common Straight Swift sightings, Taipei ranks 19th at under 5%. The best odds are in Tokyo (Japan, about 20%), Busan (South Korea, about 20%) and Daegu (South Korea, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Straight Swift is recorded against all the insects logged in Taipei (11 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.
