With luck
About 10% of wildlife watchers report a Great Pondhawk sighting in Rio de Janeiro on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 169 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March and October–January
In those months about 10% of wildlife watchers report a Great Pondhawk in Rio de Janeiro on a given day, against under 5% in February and April–September, the lowest months. Those are among Rio de Janeiro's wettest months, with about 190 mm of rain a month against 40 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Great Pondhawk sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 19
Of the 19 cities where we can rate Great Pondhawk sightings, Rio de Janeiro ranks 8th at about 10%. The best odds are in Guayaquil (Ecuador, about 30%), San Pedro Sula (Honduras, about 20%) and Manaus (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Great Pondhawk is recorded against all the insects logged in Rio de Janeiro (14 verified sightings), 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.
