Abstract:The characteristics of nests,hatching and growth of Lanius isabellinus phoenicuroides were observed in Shihezi,Xinjiang in the breeding season of 2006 and 2007.The average clutch size of L.i.phoenicuroides was 5.67 eggs,the duration of incubation was 17 days,and nestlings were mainly nursed by their mother for 15 days in the nest.We weighed each nestlings and measured their wing length and body length once a day after they were hatched,then built the models to describe the growth and development of nestlings by using the Logistic equations.The models were highly matched the growth of nestlings with a correlation coefficients,larger than 0.99.
