摘要
2006年12月上旬—2007年2月下旬,在崇明东滩堤内次生人工湿地(鱼-蟹塘)对7种优势种水禽的昼间(6:30—17:30)行为进行了观察。结果表明:白鹭(Egretta garzetta)、苍鹭(Ardea cinerea)和斑嘴鸭(Anas poecilorhyncha)以停伫行为为主,分别占全天行为的34.09%、45.45%和54.55%;白骨顶(Fulica atra)、普通鸬鹚(Phalacrocorax carbo)取食行为较活跃,分别占全天行为的32.58%和35.00%;小(Tachybaptus ruficollis)和银鸥(Larus argentatus)游水活动分别占全天行为的44.70%和31.82%。此外,环境温度和光照与水禽活动呈正相关,与风速负相关,湿地内水位由于变化不大而对越冬水禽行为影响不显著。
From the beginning of December 2006 to the end of February 2007, observations were made on the daytime （6：30-19：30） behaviors of 7 dominant species of wintering waterfowls in the secondary artificial wetland （fish-crab pond） at Chongming Dongtan. The results indicated that Egretta garzetta, Arclea cinerea and Anas poecilorhyncha mostly showed standing still behavior, accounting for 34.09%, 45.45% and 54.55% of their whole daytime behaviors, respectively. Fulica atra and Phalacrocorax carbo preferred to feeding behavior （32.58% and 35.00%, respectively）. Swimming was the major behavior of Tachybaptus argentatus （44. 70% and 31.82%, respectively）. The waterfowls＇ activities were positively correlated with temperature and sunlight, but constant water level in the wetland had no negatively correlated with wind speed. The relatively significant effects on the behaviors of test waterfowls.
