The lesser swallow-tailed swift is now placed with the great swallow-tailed swift in the genus Panyptila that was introduced in 1847 by the German ornithologist Jean Cabanis.

GBIF citizen-science records
It is estimated from how often the Lesser Swallow-tailed Swift is recorded against all the birds logged in Tortuguero National Park (120 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.
