Possible
About 20% of wildlife watchers report a Lyell's Swift sighting in Litchfield National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 43 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Lyell's Swift is recorded against all the insects logged in Litchfield National Park (18 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.
