Rare
Under 5% of wildlife watchers report a Continental Swift sighting in Hong Kong on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 819th most-seen of the 1125 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.
July
In that month about 10% of wildlife watchers report a Continental Swift in Hong Kong on a given day, against under 5% in August to June, the lowest months. That is one of Hong Kong's wettest months, with about 190 mm of rain against 25 mm in December.
2nd of 2
Of the 2 cities where we can rate Continental Swift sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Continental Swift is recorded against all the insects logged in Hong Kong (8 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.
