Coucal, though the exact ID will be difficult. Of the 4 possibilities, one is excluded, the Black Coucal, since your specimen does not have the black Chest. The remaining 3 are the Senegal, Coppery tailed and Burchell's Coucal. Probably the Coppery tailed one should also be excluded, as there is no evidence for that in your specimen, though of course that could just be the way the light has rendered the bird's tail. That leaves the Burchell's and Senegal Coucal, and ID'ing this will depend largely on the size of the bird. My thinkinog is the Senegal Coucal, as it seems, to my eye at any rate, to be somewhat smaller than the specimens I have seen of the Burhell's Coucal. Also it's preferred habitat is tangled vegetation, though that is also applicable to the Burchell's. If you are wondering, all 4 mentioned Coucals occur South of the Sahara, as does the Green Coucal (Now that would be quite the sighting to have) and that covers the 5 Coucal listed. One minor confusing detail, some list a White browed Coucal, but still arive at 5 specimens, but it seems the consencus is that this is a variation of Burchell's Coucal, especially the young, that have a distinct white eyebrow.
OK, where do I send the bill
Here are few specimens I have photographed,
