With luck
About 10% of wildlife watchers report an Aplomado Falcon sighting in Iberá National Park on a given day, based on 208 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 143rd most-seen of the 284 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March and October
In those months about 20% of wildlife watchers report an Aplomado Falcon in Iberá National Park on a given day, against under 5% in July, the lowest month.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Aplomado Falcon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 19 parks where we can rate Aplomado Falcon sightings, Iberá National Park ranks 4th at about 10%. The best odds are in Emas National Park (Brazil, about 60%), Lauca National Park (Chile, about 20%) and Serra da Canastra National Park (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Aplomado Falcon is recorded against all the birds logged in Iberá National Park (208 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.
