Possible
About 20% of wildlife watchers report a White-browed Sparrow-Weaver sighting in Lake Nakuru National Park on a given day, based on 189 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 369 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a White-browed Sparrow-Weaver in Lake Nakuru National Park on a given day, against about 10% in February, April, July and December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-browed Sparrow-Weaver sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 33
Of the 33 parks where we can rate White-browed Sparrow-Weaver sightings, Lake Nakuru National Park ranks 22nd at about 20%. The best odds are in Meru National Park (Kenya, about 80%), Liwonde National Park (Malawi, about 80%) and Samburu National Reserve (Kenya, about 70%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the White-browed Sparrow-Weaver is recorded against all the birds logged in Lake Nakuru National Park (189 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.
