With luck
About 10% of wildlife watchers report a Red-Veined Dropwing sighting in Nairobi on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 123 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.
February and October
In those months about 20% of wildlife watchers report a Red-Veined Dropwing in Nairobi on a given day, against under 5% in January, March–May, August–September and November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red-Veined Dropwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
9th of 10
Of the 10 cities where we can rate Red-Veined Dropwing sightings, Nairobi ranks 9th at about 10%. The best odds are in Riyadh (Saudi Arabia, about 40%), Lusaka (Zambia, about 30%) and Marrakesh (Morocco, about 20%).
GBIF citizen-science records
It is estimated from how often the Red-Veined Dropwing is recorded against all the insects logged in Nairobi (5 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.
