little difference as these two cuckoos appear to use the same or a 

 very similar range of fosterers. 



The recorded hosts of the little emerald cuckoo are: 



Stachyris nigriceps 

 Stachyris ruficeps 

 Tesia cyaniventer 



Bradypterus luteoventris 

 Cisticola juncidis 

 Cettia fortipes 

 Orthotomus sutorms 

 Phylloscopus reguloides 

 Seicercus castaneiceps 



Black-throated babbler 



Red -headed babbler 



Dull slate-bellied ground 

 warbler 



Brown bush warbler 



Fantail warbler 



Strong-footed bush warbler 



Tailor-bird 



Blyth's leaf warbler 



Chestnut-headed flycatcher- 

 warbler 



Yellow backed sunbird 



Mrs. Gould's sunbird 



Little spider-hunter 



Aethopyga siparaja 

 Aethopyga gouldiae 

 Arachnothera longirostris 



C. xanthorhynchus. 



The violet cuckoo is stUl imperfectly known and will probably 

 continue to be so because of its preference for the higher branches of 

 trees where it is observed with difficulty. Eggs or young attributed to 

 it have been recorded with nine species of fosterers, chiefly warblers 

 and sunbirds, but also babblers and one flower-pecker.^ Because of 

 the close similarity of the eggs of this cuckoo and those of its close 

 relative C. maculatus and the overlapping of the ranges of the two, 

 the identifications of some of the egg records may be less than com- 

 pletely certain, but they are given here as identified by their collector- 

 observers. 



All of the known hosts are involved with the nominate, mainland 

 subspecies of the violet cuckoo. So far no one has reported any eggs 

 or young of the Philippine race, amethystinus, or the Banguey Island 

 race, bangueyensis. 



The hosts reported to date are; 

 Trichastoma abbotti 

 Napothera epilepidota 

 Alcippe nipalensis 

 Cisticola juncidis 

 Orthotomus sutorius 

 Seicercus xanthoschistus 



Abbott's babbler 



Small wren-babbler 



Nepal babbler 



Fantail warbler 



Tailor bird 



Gray-headed flycatcher-warbler
