| 摘 要： | 对云龙湖黄苇鳽(Ixobrychus sinensis)的筑巢、产卵、孵化进行了研究,并测定了黄苇鳽雏鸟阶段的几个生长指标。结果表明,黄苇鳽的筑巢期从5月下旬至6月下旬,巢用水烛叶织,并营建于水烛丛中上部;巢底距离水面1.16±0.29 m,巢-岸距离10.7±3.87 m,巢-敞水区距离2.25±1.01 m;同域巢间距平均为37.5 m;巢深4.0±0.9 cm,巢内面积161.1±48.1 cm~2;窝卵数4.6±0.9个,卵体积6.75±0.51 cm~3,卵重9.41±0.73 g;窝卵数与总卵重呈正相关,窝卵数与巢内面积相关性不显著,窝总卵重与巢内面积相关性也不显著;孵化期为15~18 d,孵化率约为82%;各项形体指标随发育日龄而增长,其中翅长增长较快。

| Abstract: | The nesting,laying and hatching of bittern(Ixobrychus sinensis) in Yun-long lake were observed,to measure several growth indexes at the nestling stage.The results showed that the nesting period of bittern was from the end of May to the end of June.Nests were weave by the leaves of rush,and built on the middle and upper part of rushes.The bottom of the nest was 1.16±0.29 m distant from the water surface,the nest was 10.7±3.87 m distant from shore,the nest was 2.25± 1.01 m distant from open water.The average distance between the two nests at the same home range was 37.5 m.The nest deep was 4.0±0.9 cm,and the nest inner-area was 161.1±48.1 cm2.The clutch size was 4.6±0.9,the egg size was 6.75±0.51 cm3,and the egg mass was 9.41±0.73 g.The clutch size and the clutch mass was positively correlated,the clutch size and the nest inner-area wasn't positively correlated,the clutch mass and the nest inner-area wasn't positively correlated too.The incubation period was 15～18 d,and hatching rate was about 82％.With the days,the various shape indexes increased,and the wings length grew faster gradually than others. |
