With luck
About 10% of wildlife watchers report a Black-and-white Shrike-flycatcher sighting in Meru National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 180th most-seen of the 243 birds 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 and March
In those months about 20% of wildlife watchers report a Black-and-white Shrike-flycatcher in Meru National Park on a given day, against under 5% in January and November, the lowest months. May and July–August have too few records to rate.
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.
4th of 7
Of the 7 parks where we can rate Black-and-white Shrike-flycatcher sightings, Meru National Park ranks 4th at about 10%. The best odds are in Kibale National Park (Uganda, about 40%), Bwindi Impenetrable National Park (Uganda, about 20%) and Semuliki National Park (Uganda, about 10%).
Same family: Platysteiridae
The closest relatives of the Black-and-white Shrike-flycatcher that you can see in Meru National Park (family Platysteiridae, Wattle-eyes and Batises) are Eastern Black-headed Batis (about 10%) and Chinspot Batis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-and-white Shrike-flycatcher is recorded against all the birds logged in Meru National Park (11 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.
