It is native to the African highlands from Ethiopia and Kenya through Rwanda to eastern Zaire and Malawi. The sub-species M. f. toruensis occurs in Rwanda and Burundi and has an inconspicuous eye-ring.

Possible
About 30% of wildlife watchers report a White-eyed Slaty Flycatcher sighting in Nairobi National Park on a given day, based on 434 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th 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–July, October and December
In those months about 30% of wildlife watchers report a White-eyed Slaty Flycatcher in Nairobi National Park on a given day, against about 20% in January–February, August–September and November, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most White-eyed Slaty Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 13
Of the 13 parks where we can rate White-eyed Slaty Flycatcher sightings, Nairobi National Park ranks 8th at about 30%. The best odds are in Aberdare National Park (Kenya, about 60%), Arusha National Park (Tanzania, about 50%) and Volcanoes National Park (Rwanda, about 50%). All parks ranked.
Same family: Muscicapidae
The closest relatives of the White-eyed Slaty Flycatcher that you can see in Nairobi National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Cape Robin-Chat (about 40%), White-browed Scrub Robin (about 40%) and African Gray Flycatcher (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-eyed Slaty Flycatcher is recorded against all the birds logged in Nairobi National Park (434 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.
