ALLOXENIA — FRIEDMANN 



sidering each of these host catalogs, the reader should keep in mind 

 that these lists will grow steadily as additional field data become 

 available and that we may well find it necessary to reappraise the 

 apparent preferences of the third and least known species.

As noted earlier, 93, or more than two-thirds of all these records, 

 involve thrushes, and 62 of these involve eight species of a single 

 genus of fosterers, Cossypha, the robin chats. The only other thrushes 

 for which there are numerous records are Saxicola torquata (two races) 

 with eight cases, Monticola rupestris with six instances, and Pinarornis 

 plumosus with four cases; all the other thrushes have only one or two 

 records apiece. 



Next in frequency of choice as hosts are the wagtails and pipits 

 (family Motacillidae) with 21 records involving four species. Here it 

 should be observed that the pipits (Anthus) are not very important
