With luck
About 10% of wildlife watchers report a Black-and-white Shrike-flycatcher sighting in Kampala on a given day, based on 180 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 332 birds 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.
January–August and October–November
In those months about 10% of wildlife watchers report a Black-and-white Shrike-flycatcher in Kampala on a given day, against under 5% in September and December, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-and-white Shrike-flycatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Black-and-white Shrike-flycatcher sightings, Kampala ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Freetown (Sierra Leone, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-and-white Shrike-flycatcher is recorded against all the birds logged in Kampala (180 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.
