Of the 59 hosts tabulated above, 30 figure in the list on the basis 

 of single records; 11 others are birds for which I have been able to 

 learn of two instances each; two have been reported as fosterers of 

 Klaas's cuckoo 3 times and two others 4 times each. 



C. cupreus. 



The emerald cuckoo of Africa has been found to parasitize a good 

 number and a wide variety of small passerine birds. Data are available 

 on 60 instances of its parasitism, involving 34 species of hosts (42 

 species and subspecies).® 



Unlike C. caprius, which is primarily parasitic on weavers, and C. 

 Haas, which affects sunbirds and warblers more than any other birds, 

 the present species cannot be said to favor one particular family of 

 hosts. The most frequently reported fosterer is a bulbid, Pycnonotus 

 barbatus, for which there are nine records; then, with four records 

 apiece, are a weaver, Ploceus cucullatus, a sunbird, Necfarinia erythro- 

 ceria, and a flycatcher, Terpsiphone viridis; following these, with 

 three records each, are a shrike, Dryoscopus cubla, two sunbirds,
