The grey cuckooshrike (Ceblepyris caesius) is a species of bird in the cuckooshrike family Campephagidae. It is a medium-sized forest bird, with grey to blue-grey plumage and large black eyes. There are two subspecies that occur in forest patches of southern and central Africa respectively.
The grey cuckooshrike belongs to the family Campephagidae of the old world songbirds. There are almost 90 species within Campephagidae that occur in Africa, Asia and Australasia. Ceblepyris caesia is often considered to be part of a superspecies with the white-breasted cuckooshrike (Ceblepyris pectoralis); which looks somewhat similar apart from the striking white underparts compared to C. caesia's grey underparts. The grey cuckooshrike is also found at higher elevation than its white-breasted counterpart. A 2010 genetic analysis confirmed the two species as each other's closest relatives, with their common ancestor diverging from the ancestor of Grauer's cuckooshrike.
"Grey cuckooshrike" has been designated the official name by the International Ornithologists' Union (IOC). The species is also commonly referred to as the mountain grey cuckooshrike and the African grey cuckooshrike... Wikipedia →

Possible
About 20% of wildlife watchers report a Grey Cuckoo-Shrike sighting in Nyungwe National Park on a given day, based on 253 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 74th most-seen of the 252 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Grey Cuckoo-Shrike in Nyungwe National Park on a given day, against about 10% in February–June and August, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Grey Cuckoo-Shrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 7 parks where we can rate Grey Cuckoo-Shrike sightings, Nyungwe National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Bwindi Impenetrable National Park (Uganda, about 20%).
GBIF citizen-science records
It is estimated from how often the Grey Cuckoo-Shrike is recorded against all the birds logged in Nyungwe National Park (253 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.
