pecker feeding a fledgling great-spotted cuckoo about a week out of 

 the nest. This is the only record known to me of this woodpecker 

 as a host, 



Corvus corone Linnaeus Hooded Crow 



Two races of this crow have been found to be victimized by the 

 great-spotted cuckoo, the nominate form in southern Spain (one 

 record, now in the British Museum) and the race sardonius in Israel 

 and in Egypt. In the last-named country the hooded crow is the chief, 

 if not the invariable, host, and, in all, over 50 Egyptian instances 

 have come to my attention. The numerical relations between host and 

 parasite eggs there are shown in our graph (fig. 10, p. 43), which 

 gives a picture quite different from that of other crows south of the 

 Sahara. 



Corvus ruficollis Lesson Brown-necked Raven 



According to Archer (in Archer and Godman, 1961, vol. 3, pp. 

 649-659) the local race (edithae) of this bird is the chief host of the 

 great-spotted cuckoo in former British Somaliland (now part of the 

 Somali Republic). He gave data on five instances from his fieldwork 

 in that area, the actual localities being Arori Plain, Burao, Baraad, 

 and Oadweina. Two other parasitized nests were collected by M. E. 

 W. North, at Brava, former Italian Somaliland (now part of the 

 Somali Republic), and sent to the Coryndon Museum. I am indebted 

 to J. G. Williams for information about them. Belcher (1949, p. 37) 

 reported another parasitized nest near Gabredarre, Ogaden, former 

 Italian Somaliland (now a part of the Somali Republic). In this 

 case, the nest contained a nestling of the host in addition to eggs 

 of its own and of the parasite. 



Corvus corax Linnaeus Raven 



Hartert (1912, p. 956) recorded this bird (typical race) as a host 

 of the great-spotted cuckoo in Spain, but the basis for this statement 

 is not given; Valverde (1953, p. 294) notes it as found by Lord 

 Lilford at Aranjuez. It remains a unique record. The only para- 

 sitized set of eggs of any species of Corvus from Spain that I know 

 of is a set of Corvus corone in the British Museum. 



Corvus albus Miiller Pied Crow 



The number of records of this crow as a victim of the great-spotted 

 cuckoo has been more than doubled since my first (1949a, pp. 11-12)
