FURTHER DATA ON AFRICAN PARASITIC CUCKOOS 



By Herbert Friedmann 



The data assembled in this paper extend our knowledge of African 

 parasitic cuckoos from the basic facts presented in my book entitled 

 "The Parasitic Cuckoos of Africa" published in 1949 and the little 

 addendum to it (Friedmann, 1949b) published later in the same year. 

 In the present account only those data pertinent to the problems of 

 parasitic reproduction are included. For this reason, some species 

 of cuckoos are not discussed at all as there were no new facts to 

 describe. Even in those that are treated in this paper almost no 

 space is given to such items as call-notes, migration, food of the adult, 

 plumages, etc. 



For sending me unpublished information, for answering many 

 queries, and for other acts of kind cooperation, I am indebted to the 

 following naturalists: C. F. Belcher, J. P. Chapin, F. Haverschmidt, 

 R. Liversidge, P. Millstein, E. Pike, O. P. M. Prozesky, R. A. Reed, 

 and W. Stanford. The photographs illustrating this paper were 

 supplied by Mr. Liversidge in addition to his information. His 

 observations on the red-chested cuckoo (Liversidge, 1955), unpub- 

 lished when sent to me, fortunately appeared in print just as the 

 present manuscript was about to leave my hands. I have therefore 

 merely summarized his data insofar as integrating all the information 

 has permitted.
