The African cuckoo or African grey cuckoo (Cuculus gularis) is a species of cuckoo in the family Cuculidae. It is found in Sub-Saharan Africa where it migrates within the continent, generally arriving and breeding in any one locality during the rainy season. A fairly common bird, the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
This is a medium-sized species with a long tail, with a total length of 32 cm (13 in). Its dashing flight makes it resemble a bird of prey. The sexes are similar, the head, upper parts and wings being dark grey, the throat and breast pale grey and the belly white barred with dark grey. The tail is dark grey with dark barring and a white tip. The eye is yellow in the male and light brown in the female. The beak is yellow, tipped with black or horn. The legs and feet are yellowish. The juvenile has two colour forms; the grey morph is greyer than the adult with white barring, the underparts being creamy-white with dense dark barring; the hepatic morph is brown rather than grey, the white being replaced by buff or a tawny hue. The call of the male is a "coo-coo" with the second note... Wikipedia →
With luck
About 10% of wildlife watchers report an African Cuckoo sighting in Ngorongoro Conservation Area on a given day, based on 145 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 234th most-seen of the 519 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report an African Cuckoo in Ngorongoro Conservation Area on a given day, against under 5% in May to December, the lowest months. That is one of Ngorongoro Conservation Area's wettest months, with about 190 mm of rain against almost none in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most African Cuckoo 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 28 parks where we can rate African Cuckoo sightings, Ngorongoro Conservation Area ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Lake Mburo National Park (Uganda, about 10%), Meru National Park (Kenya, about 10%) and Tarangire National Park (Tanzania, about 10%).
GBIF citizen-science records
It is estimated from how often the African Cuckoo is recorded against all the birds logged in Ngorongoro Conservation Area (145 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.
