With luck
About 10% of wildlife watchers report a Narrow-Winged Grey sighting in Doñana National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 87 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Narrow-Winged Grey in Doñana National Park on a given day, against under 5% in May to February, the lowest months.

Across all the parks we cover, that three-hour window holds the most Narrow-Winged Grey sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 6
Of the 6 parks where we can rate Narrow-Winged Grey sightings, Doñana National Park ranks 3rd at about 10%. The best odds are in Monfragüe National Park (Spain, about 20%) and Cévennes National Park (France, about 10%).

GBIF citizen-science records
It is estimated from how often the Narrow-Winged Grey is recorded against all the insects logged in Doñana National Park (8 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.
