Rare
Under 5% of wildlife watchers report a Buckley's Forest Falcon sighting in Yasuní National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 502nd most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Buckley's Forest Falcon in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Buckley's Forest Falcon sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 3 parks where we can rate Buckley's Forest Falcon sightings, Yasuní National Park ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Tambopata National Reserve (Peru, under 5%) and Manu National Park (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Buckley's Forest Falcon is recorded against all the birds logged in Yasuní National Park (11 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.
