| Abstract: | From May to July in 2010,three nests of Lanius isabellinus were found to be parasitized by common cuckoo Cuculus canorus in Gansu Anxi National Nature Reserve in Hyper-arid Desert,the parasitism rate was 10.34%.There are two colors of L.isabellinus eggs,white and pink.However,only the hosts with white eggs were parasitized by common cuckoo,moreover,the color of host eggs were all white.The parasitism rate was 42.86% in June because brood parasitism was only observed in this month.Nestling period lasted 19 days,the fledging body weight was 66.24 g before leaving the nest.Nest success rate was 66.67%. |
