Likely
About 50% of wildlife watchers report a White-eyed Slaty Flycatcher sighting in Arusha National Park on a given day, based on 370 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 373 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 70% of wildlife watchers report a White-eyed Slaty Flycatcher in Arusha National Park on a given day, against about 30% in January, the lowest month. That is one of Arusha National Park's wettest months, with about 440 mm of rain against 65 mm in September.
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.
2nd of 13
Of the 13 parks where we can rate White-eyed Slaty Flycatcher sightings, Arusha National Park ranks 2nd at about 50%. The best odds are in Aberdare National Park (Kenya, about 60%). All parks ranked.
Same family: Muscicapidae
The closest relatives of the White-eyed Slaty Flycatcher that you can see in Arusha National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are African Dusky Flycatcher (about 60%), African Stonechat (about 50%) and Rüppell's Robin-Chat (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 Arusha National Park (370 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.
