The great spotted cuckoo (Clamator glandarius) is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis and the coucals. It is widely spread throughout Africa and the Mediterranean Basin. It is a brood parasite that lays its eggs in the nests of corvids, in particular the Eurasian magpie.
In 1747 the English naturalist George Edwards included an illustration and a description of the great spotted cuckoo in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Great Spotted Cuckow". Edwards based his hand-coloured etching on a specimen that had been shot in Gibraltar and sent to the English naturalist Mark Catesby in London. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the great spotted cuckoo with the other cuckoos in the genus Cuculus. Linnaeus included a brief description, coined the binomial name Cuculus glandarius and cited Edwards's work. The great spotted cuckoo is now placed in the genus Clamator that was introduced by German naturalist Johann Jakob Kaup in 1829. The species is monotypic: no subspecies are recognised... Wikipedia →

Rare
Under 5% of wildlife watchers report a Great Spotted Cuckoo sighting in Ruaha National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 242nd most-seen of the 276 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Great Spotted Cuckoo in Ruaha National Park on a given day, against under 5% in March to December, the lowest months. Those are among Ruaha National Park's wettest months, with about 150 mm of rain a month against almost none in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Great Spotted Cuckoo sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 25
Of the 25 parks where we can rate Great Spotted Cuckoo sightings, Ruaha National Park ranks 8th at under 5%. The best odds are in Meru National Park (Kenya, about 10%), Awash National Park (Ethiopia, about 10%) and Serengeti National Park (Tanzania, about 10%).
Same genus: Clamator
The closest relatives of the Great Spotted Cuckoo that you can see in Ruaha National Park (genus Clamator, Old World Crested Cuckoos) are Jacobin Cuckoo (about 10%) and Levaillant's Cuckoo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Spotted Cuckoo is recorded against all the birds logged in Ruaha National Park (7 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.
