With luck
About 10% of wildlife watchers report a Walker's Owl sighting in Nairobi on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 123 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.
February
In that month about 30% of wildlife watchers report a Walker's Owl in Nairobi on a given day, against under 5% in June–September and December–January, the lowest months. That is one of Nairobi's driest months, with about 30 mm of rain against 150 mm in April.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Walker's Owl sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 2 cities where we can rate Walker's Owl sightings, Nairobi has the highest daily chance: about 10%. Next come Durban (South Africa, about 10%).
Same family: Erebidae
The closest relatives of the Walker's Owl that you can see in Nairobi (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Sundowner Moth (about 10%), Creamstriped Owl (about 10%) and Small Cloth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Walker's Owl is recorded against all the insects logged in Nairobi (8 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.
