Rare
Under 5% of wildlife watchers report a Lesser Swallow-tailed Swift sighting in Tambopata National Reserve on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 451st most-seen of the 550 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lesser Swallow-tailed Swift in Tambopata National Reserve on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Lesser Swallow-tailed Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
29th of 35
Of the 35 parks where we can rate Lesser Swallow-tailed Swift sightings, Tambopata National Reserve ranks 29th at under 5%. The best odds are in Bastimentos Island National Marine Park (Panama, about 20%), Tikal National Park (Guatemala, about 10%) and Soberanía National Park (Panama, about 10%).

GBIF citizen-science records
It is estimated from how often the Lesser Swallow-tailed Swift is recorded against all the birds logged in Tambopata National Reserve (24 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.
