some 2Z records, account for half of the total. The known hosts are 

 as follows: 



Phoeniculus purpureas zuluensis Turdoides jardinei jardinei 



Colius striatus striatus Turdoides jardinei natal ensis 



Pycnonotus barbatus minor Turdoides jardinei kirki 



Pycnonotus barbatus layardi Turdoides jardinei emini 



Phyllanthus atripennis bohndorffi Turdoides jardinei tanganjicae 



Turdoides plebeja gularis Turdoides reinwardii reinwardii 



Turdoides plebeja cinereus Turdoides leucopygia hartlaubii 



Turdoides plebeja plebeja Turdoides bicolor 



Turdoides plebeja platycircus Cossypha caffra caffra 



Of these 10 species, the first is not more than an accidental choice, 

 and is based on a questionable identification of the parasitic egg 

 (Roberts, 1939a, pp. 10-13). In addition to these it may be added 

 that Bradfield (1931, pp. 7-9) suggested that in Damaraland the 

 Burchell starling, Lamprotornis australis, was also parasitized, but 

 he had no evidence other than that he had noted these starlings 

 "mobbing" a stripe-breasted cuckoo, 



Clamator coromandus (fig. 5, p. 16) 



The red-winged cuckoo is parasitic chiefly on babblers, and, within 

 this group, primarily on the larger laughing-thrushes of the genus 

 Garnilax, some 13 species of which have been found to be victimized. 

 Baker (1942, pp. 196-197) listed 265 eggs of the red-winged cuckoo 

 in his collection, taken from nests of 21 species (25 species and 

 subspecies) of hosts. Of these 265, all but 24 were found in nests 

 of Garrulax, and no fewer than 109 from nests of a single species, 

 the necklaced laughing-thrush, G. moniligera, and 37 from nests of 

 the black-gorgeted laughing-thrush, G. pectoralis. 



Our knowledge of this cuckoo's fosterers is still largely based on 

 collections and observations from the Indian and Burmese portions 

 of its range. In due time many hosts from other areas will be added 

 to the list. The following list of known victims is based on that of 

 Baker, with a few additions from other sources.
