我们记录了研究较少的大鹰鹃对一种以前未知的寄主--中国Babax的亲卵寄生。此外，我们描述了新的鸡蛋颜色的大鹰杜鹃。中国Babax巢4年的寄生率为6.9%（11/159巢），具有显著的时间变化。大鹰杜鹃产下的白色卵与蓝色Babax卵无相似性，鸟类视觉模拟证实了这一现象。然而，大多数杜鹃卵被宿主接受，表明这种宿主-寄生系统可能是进化最近的。
Department of Biology, Norwegian University of Scienceand Technology (NTNU), NO-7491 Trondheim, NorwayWe documented brood parasitism by the poorly studiedLarge Hawk-Cuckoo on a previously unknown host spe-cies, the Chinese Babax. Furthermore, we describe anew egg colour for the Large Hawk-Cuckoo. The parasit-ism rate of Chinese Babax nests over 4 years was 6.9%(11 of 159 nests), with significant temporal variation.The Large Hawk-Cuckoo laid immaculate white eggsthat appeared non-mimetic to the blue Babax eggs, animpression that was confirmed by avian visual modelling.Nevertheless, most Cuckoo eggs were accepted by thehost, suggesting that this host–parasite system may beevolutionarily recent.
