要掌握好噴射時間適好在卵孵化的末期。This incubation adjustment of parents makes the synchrony in hatching and the hatching intervals of nestlings shorter than the laying intervals of eggs. this phenomenon was perhaps resulted from the incubating behavior difference of parents in laying time and incubating time. the research also found that the growth rate and survival rate in the latest hatched nestlings in little egret were lower than the earlier hatched ones
卵的孵化時間與產卵順序呈負相關性，先產的卵比后產的卵所需孵化時間相對較長，此現象產生是由於親鳥在產卵期和產卵后的孵化行為不一致造成的，這種孵化調節使同一窩雛鳥孵出時間具有相對集中的趨勢，雛鳥出殼的時間間隔比產卵的時間間隔短；另一方面，在白鷺雛鳥的生長過程中，最晚出殼的雛鳥生長水平和成活率明顯落後于早出殼的雛鳥，而池鷺由於窩卵數和窩雛數為5的數量相對較少，雛鳥生長均衡。The development process, from fertilized egg to spiracular formation can be divided into 26 stages, took 212. 94 hours under the water temperature of ( 20 0. 5 ) and 170. 95 hours under the natural temperature ( 21. 5 24 ). the external morphological characteristics in various stages of the embryonic development were similar to those of rana nigromaculata, but the hatching stage was later than that of rana nigromaculata and earlier than that of rana limnocharis
