Possible
About 20% of wildlife watchers report a Moustached Grass-Warbler sighting in Nairobi National Park on a given day, based on 403 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 105th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March–June and November–December
In those months about 30% of wildlife watchers report a Moustached Grass-Warbler in Nairobi National Park on a given day, against about 20% in January–February and July–October, the lowest months. Those are among Nairobi National Park's wettest months, with about 100 mm of rain a month against 15 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Moustached Grass-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.
3rd of 14
Of the 14 parks where we can rate Moustached Grass-Warbler sightings, Nairobi National Park ranks 3rd at about 20%. The best odds are in Kidepo Valley National Park (Uganda, about 50%) and Arusha National Park (Tanzania, about 40%).
GBIF citizen-science records
It is estimated from how often the Moustached Grass-Warbler is recorded against all the birds logged in Nairobi National Park (403 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.
