通过多年的调查资料、观鸟爱好者所提供的图片和文献整理,我们对多杜鹃寄生系统下的中国寄生性杜鹃及其宿主的多样性进行了系统研究.在中国分布的17种寄生性杜鹃中,迄今已发现11种杜鹃的宿主达55种,均为雀形目鸟类,隶属于15科,其中莺科、鸫科和画眉科分别占到寄生记录总数的22.6％、20.8％和17.0％.大杜鹃(Cuculus canorus)的宿主种类最多(45.5％),是中国最常见、宿主多样性最丰富的寄生性杜鹃.不同种类的寄生性杜鹃的卵色不同,而且杜鹃与其宿主之间均呈现明显的卵色多态性,为典型的卵色协同进化.基于人眼观察,大杜鹃、小杜鹃(C.poliocephalus)和八声杜鹃(Cacomantis merulinus)的卵色均与其宿主高度模拟,而鹰鹃(Cuculus sparverioides)、中杜鹃(C.saturatus)和翠金鹃(Chrysococcyx maculatus)则产非模拟的卵.目前仍有6种寄生性杜鹃的宿主不详,亟待加强研究.

In this exposé we provide the first review of host use by brood parasitic cuckoos in a multiple-cuckoo system in China,based on our own long-term field data and a compilation of observations obtained from the literature.In total,we found that 11 species of cuckoos utilized altogether 55 host species.These hosts belong to 15 families,in which Sylviidae,Turdidae and Timaliidae account for 22.6％,20.8％ and 17.0％ of parasitism records,respectively.The Common Cuckoo (Cuculus canorus) had the widest range of host species,accounting for 45.5％ of the total number of parasitized species (25 in 10 families) of all parasitism records and is the most frequent brood parasite in the country.Cuckoo species differed in their egg coloration and the extent of egg polymorphism with most of them,e.g.the Common Cuckoo,the Lesser Cuckoo (C.poliocephalus)and the Plaintive Cuckoo (Cacomantis merulinus) laying well mimetic eggs with respect to their hosts based on human being's visual observations,while others such as the Large Hawk-cuckoo (C.sparverioides),the Himalayan Cuckoo (C.saturatus) and the Asian Emerald Cuckoo (Chrysococcyx maculatus) usually laid non-mimetic eggs.The use of cuckoo hosts and egg color variation in China are compared with those in other parts of their ranges in Asia.
