Rare
Under 5% of wildlife watchers report a Croocked Swift sighting in Johannesburg on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 213 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
November to February
In those months about 10% of wildlife watchers report a Croocked Swift in Johannesburg on a given day, against under 5% in March to October, the lowest months. Those are among Johannesburg's wettest months, with about 110 mm of rain a month against almost none in July.
Only Johannesburg, in our data
Johannesburg is the only city on Wallace's Line with enough records to rate Croocked Swift sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Croocked Swift that you can see in Johannesburg (order Lepidoptera, Butterflies and Moths) are Garden Acraea (about 30%), Creamstriped Owl (about 30%) and Junonia archesia (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Croocked Swift is recorded against all the insects logged in Johannesburg (7 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.
