The black cuckoo (Cuculus clamosus) is a species of cuckoo in the family Cuculidae. The species is distributed widely across sub-Saharan Africa. There are two subspecies. This cuckoo has a very wide range and is quite common so it is classified as a least-concern species by the International Union for Conservation of Nature.
The black cuckoo is a medium-sized cuckoo. The sexes are similar, the plumage varying by subspecies; Cuculus clamosus clamosus has upper parts black glossed with green, slatey-grey wings and black tail tipped with white and sometimes with the outer feathers barred or spotted with white or buff; Cuculus clamosus gabonensis is mostly black with a red throat and black and white barring on the belly.
The subspecies Cuculus clamosus gabonensis is a resident in Central Africa, whereas the Southern African subspecies Cuculus clamosus clamosus is migratory, breeding in Southern Africa in September to December, then moving in March to Central, Eastern and West Africa. The range of this species extends from Liberia to Ethiopia in the east and Angola and South Africa. It is a woodland bird but avoids the interior of dense forests... Wikipedia →

With luck
About 10% of wildlife watchers report a Black Cuckoo sighting in Tsavo West National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 218th most-seen of the 380 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.

GBIF citizen-science records
It is estimated from how often the Black Cuckoo is recorded against all the birds logged in Tsavo West National Park (50 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.
