Rare
Under 5% of wildlife watchers report a Brown Warbler sighting in Nairobi National Park on a given day, based on 63 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 254th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January, March, May and November
In those months about 10% of wildlife watchers report a Brown Warbler in Nairobi National Park on a given day, against under 5% in February, April, June–October and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Brown Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 parks where we can rate Brown Warbler sightings, Nairobi National Park ranks 2nd at under 5%. The best odds are in Bale Mountains National Park (Ethiopia, about 20%).
GBIF citizen-science records
It is estimated from how often the Brown Warbler is recorded against all the birds logged in Nairobi National Park (63 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.
