主　　题：Cuculus saturatus distance to forest parasitism risk Pycnonotus xanthorrhous Spizixos semitorques 

摘      要：Selection due to cuckoo parasitism is responsible for the evolution of anti-parasitism defenses in *** host species breeding sympatrically with a single parasitic cuckoo may evolve different strategies to reduce the risk of counter cuckoo parasitism,resulting in different interactions between cuckoos and hosts in areas of ***,we studied the coevolutionary interactions between Himalayan cuckoos Cuculus saturatus and 2 sympatric and closely related potential hosts belonging to the family Pycnonotidae,the brown-breasted bulbul Pycnonotus xanthorrhous and the collared finchbill Spizixos *** investigated parasitism rates and nest-site selection(nest height,nest cover,human disturbance,perch height,forest distance,and degree of concealment)related to parasitism risk,nest defense against a cuckoo dummy,and egg rejection against cuckoo model *** used specific nest sites that were further away from forests than those of finchbills,and they behaved more aggressively toward cuckoos than *** contrast,bulbuls possessed moderate egg rejection ability,whereas the finchbill rejected 100%of cuckoo model *** suggest that selection of a nest site away from forests by the bulbul explains the absence of parasitism by Himalayan *** suggest that these interspecific differences in nest-site selection and nest defense indicate alternative responses to selection due to cuckoos.
