With luck
About 10% of wildlife watchers report a Lesser-Horned Swift sighting in iSimangaliso Wetland Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 77th most-seen of the 316 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Lesser-Horned Swift in iSimangaliso Wetland Park on a given day, against under 5% in January, September and November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Lesser-Horned Swift sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only iSimangaliso Wetland Park, in our data
iSimangaliso Wetland Park is the only park on Wallace's Line with enough records to rate Lesser-Horned Swift sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lesser-Horned Swift is recorded against all the insects logged in iSimangaliso Wetland Park (27 verified sightings from 2019 to 2026), 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.
