摘　　要：2002年始,在江苏大丰麋鹿国家级自然保护区持续观测到东方白鹳。2006年一些东方白鹳个体开始在保护区内繁殖,但至今仅2010年繁殖成功。为了解该物种在保护区内的种群繁殖特征,2010年2～6月,对繁殖期东方白鹳亲鸟的行为进行了观察,并测量了巢和巢址参数,结果如下:东方白鹳的2个巢都筑在刺槐树上,巢材为附近植物的条枝,巢内有内垫物。巢周围生境为狼尾草,巢区面积7.2 hm。。繁殖不同时期,在巢、翻卵、育雏3种行为差异极显著(P<0.01);飞翔、交配、取材、其他行为差异显著(0.01<P<0.05);而理羽、警戒、觅食、行走、击喙、整巢、视野外行为则差异不显著(P>0.05)。Since 2002,a small population of oriental white stork（Ciconia boyciana） has occupied Jiangsu Dafeng Milu National Nature Reserve.From 2006,the storks attempted to breed,but only succeeded in 2010.We studied breeding behavior and calculated nest indices from February to June in 2010.Two nests were built on black locust（Robinia pseudoacacia） trees.The nest materials were the branches of nearby trees and the nests were lined.The habitat of the nest was Chinese Pennisetum（R.pseudoacacia） and the area of the nest zone was 7.2 ha.Activity budgets for on - nest,egg turning - over,feeding differed significantly by stage of the breeding period（P0.01）,as did budgets for flying,mating, fetching material and other activities（0.01 P 0.05 ）.Preening,vigilance,foraging,walking,bill clattering,nest repair and unknown behaviors showed no significant difference（P 0.05 ） by stage of the breeding period.
