The white-eyed slaty flycatcher (Melaenornis fischeri) is a small passerine bird of the genus Melaenornis in the Old World flycatcher family Muscicapidae. 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.
The specific epithet commemorates the German explorer Gustav Adolf Fischer. http://www.kenyabirds.org.uk/slaty.htm Archived 2007-04-15 at the Wayback Machine Wikipedia →

Likely
About 40% of wildlife watchers report a White-eyed Slaty Flycatcher sighting in Nairobi on a given day, based on 607 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 234 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a White-eyed Slaty Flycatcher in Nairobi on a given day, against about 30% in August–September and November, the lowest months. That is one of Nairobi's driest months, with about 25 mm of rain against 150 mm in April.
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.
Yes
Of the 2 cities where we can rate White-eyed Slaty Flycatcher sightings, Nairobi has the highest daily chance: about 40%. Next come Kigali (Rwanda, under 5%).
Same family: Muscicapidae
The closest relatives of the White-eyed Slaty Flycatcher that you can see in Nairobi (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Rüppell's Robin-Chat (about 40%), Cape Robin-Chat (about 20%) and African Dusky Flycatcher (about 20%), 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 (607 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.
