Pogonocichla swynnertoni: One record, a nest containing a red-chested cuckoo 

 egg, found at Stapleford, near Umtali, Southern Rhodesia, Jan. 8, 1963, by A. 

 Williams and reported to me by R. K. Brooke. 



Cossypha semirufa intercedens: In the Ngong area, Kenya, van Someren (1956, 

 p. 306) reported this as the chief victim of the red-chested cuckoo, writing that 

 the "three pairs of cossyphas that nest near my stream are regularly victimized; 

 they seldom raise a brood of their own . . . ." 



Cossypha cyanocampter bartteloti: van Someren (in litt., May 14, 1961) reported 

 a female of this thrush caring for a young red-chested cuckoo in the Kyetume area, 

 Uganda, in 1912. 



Cossypha niveicapilla melanonota: van Someren (in litt., May 14, 1961) wrote 

 me that in 1913 he found several nests of this robin chat, each with an egg of the 

 red-chested cuckoo, in the Mabira Forest, Uganda. It is not possible at this late 

 date to check this statement, but it should be noted that the black cuckoo, C. 

 clamosus jacksoni, also occurs in the Mabira Forest. 



Neocossyphus poensis praepectoralis: Listed as a host in Fernando Poo by Basilio 

 (1963). 



Stizorhina fraseri fraseri- Said to be victimized in the island of Fernando Poo 

 (Basilio, 1963). 



Turdus libonyanus tropicalis: Pitman (1961, pp. 48-49) lists three instances of 

 parasitism on this thrush by the red-chested cuckoo, all in Southern Rhodesia. 



Muscicapa adusta adusta: One additional record for this seldom-used host has 

 come to my attention from R. I. G. Attwell (in litt., Apr. 10, 1963), who found 

 a pair of these flycatchers with a fledgling red-chested cuckoo at Knysna, Cape 

 Province, Dec. 28, 1962. 



Terpsiphone rufiventer tricolor: Listed as a host in Fernando Poo by Basilio 

 (1963). 



Terpsiphone viridis viridis: Jessop (1960, p. 179) reported a nest of this paradise 

 flycatcher with a red-chested cuckoo's egg near the Sir Lowry's Pass River, Cape 

 Province, on November 4, 1956. 



Cuculus clamosus 



The list of hosts of the black cuckoo presented in this paper in- 

 cludes a few on which further data should be presented: 



Pinarornis plumosus: One record is known of this babbler as a host of the black 

 cuckoo. McLean (1957) found a parasitized nest at Que Que Reserve, Southern 

 Rhodesia, November 26. He saw the cuckoo fly out of the nest, which, on inspec- 

 tion, was found to contain one egg of the parasite and two of the host. 



Laniarius barbarus atrococcineus: The known instances of parasitism on this 

 shrike recently have been doubled. Rowan, Skead, and Winterbottom (1964, p. 

 235) noted that a pair of these shrikes was seen caring for a fledgling black cuckoo 

 at Hoffnung, Damaraland, February 11. In the Wankie Game Reserve, Southern 

 Rhodesia, Vernon (in litt., 1961) made a similar observation in January 1958. 



Oriolus auratus: To the single instance mentioned in my earlier (1949a) list 

 may be added a second one. Benson and Pitman (1956, p. 25) found a nest at 

 Kasana, Zambia, November 14, containing two newly hatched young, one of 

 which turned out to be a black cuckoo and became the sole occupant of the nest 

 five days later. 



Cossypha natalensis: Oatley (1959, p. 431) recorded this robin chat as a victim 

 of both the black and the red-chested cuckoo. Previously only a single record of its 

 serving as a host to the black cuckoo was known to me.
