概要 We studied clutch size, reproductive success and growth rate of the Little Egerts Egretta garzetta in three mixed species heronries in Pyongtaek, Korea, 2000. The mean clutch size of the Little Egrets... was 3.48±0.93eggs, and the mean initial brood size was 2.65±1.90 chics, and mean final blood size was 2. 86±0.90 chicks. The initial Blood size was highly significant between clutch sizes (ANOVA,p<0.01), and final blood size was high difference not only between clutch sizes but also between initial brood sizes (ANOVA,p<0.01). Hatching success and fledging success was highly significant between clutch sizes(ANOVA,p<0.01). Growth rate between initial brood size, weight(ANOVA,p<0.05), culme length (ANOVA,p<0.01) and wing length (ANOVA,p<0.01) had significantly different. Between hatching orders per nest, culmen (ANOVA,p<0.05) and wing (t-test, p<0.05) length has significantly different in initial blood size 3 and in initial blood size2, resoectively. However, tarsus-length growth rate was not significant between hatching orders, and between initial blood sizes.続きを見る
