possibly the fact that basalis is not numerous in his area may help to 

 maintain their host electivity to so high a degree. Several authors have 

 written of M. cyaneus that it is the most frequent host for basalis, 

 some even calling it the "invariable" one. The thornbills, Acanthiza, 

 also with 10 species, account for 58 records, or 15 percent of the total. 

 The most frequently imposed upon of these birds is the yellow-tailed 

 thornbill, A. chrysorrhoa, with 18 records, followed by three other 

 species, A. pusilla with 11 records, A. uropygialis with 9, and A. 

 reguloides with 8. The robins of the genus Petroica, involving 5 species, 

 have been found to be parasitized 29 times, with the scarlet robin, 

 P. multicolor, leading with 11 records, the red-capped robin, P. good- 

 enovii with 10, the hooded robin, P. cucullata, with 4, the rose robin, 

 P. rosea, with 3, whUe the flame robin, P. phoenicea, is known by me 

 as a host on the basis of a single report. 



Honeyeaters, family Meliphagidae, with 21 species involved, figure 

 on the list with a total of 39 records, with 5 reported instances for 

 one of the species, the tawny-crowned honeyeater, Gliciphila melanops, 

 4 cases for the yellow-winged honeyeater, Meliornis novaehollandiae, 

 and 3 or fewer for the rest. 



As might have been expected, small passerine birds are the regular 

 hosts of this cuckoo, the one record for the diamond dove being an 

 obvious "freak" occurrence.
