摘  要:
2007年10月至2008年3月和2008年10月至2009年3月,连续两年在江西省中华秋沙鸭(Mergus squamatus)弋阳越冬区,对其越冬习性进行了初步研究。采用直接观察法观测和记录了中华秋沙鸭越冬区的环境因子及其在越冬期的活动情况。结果表明,中华秋沙鸭在每年的10月下旬至12上旬陆续到达弋阳越冬区,翌年2月末至3月中下旬先后迁离,居留时间在120 d左右。其对越冬地的环境要求较高,选择的越冬地一般受外界的干扰少,越冬期的各项活动也保持一定的规律性。在越冬期间,中华秋沙鸭在水中活动的时间占全部时间的82.4%,陆地活动时间仅占12.6%,空中飞翔的时间占5%左右,而且飞行高度和距离都比较小。

摘  要:
Overwintering behavior of Mergus squamatus was studied in Yiyang wintering habitat from October 2007 to March 2008 and October 2008 to March 2009.We made continuous observation on the circumstance factor and activity behaviors in its wintering period.The results showed that Mergus squamatus migrated to Yiyang wingtering habitat from October to December each year.They spent about 120 days in their wintering area.Their requests for wintering condition were very high.They chose little outside interference as their habitat,and their wintering habitat activities were orderly.They spent 82.4% of their activity time in water and 12.6% on land,their flying time was only about 5%.Their flying height and distance was small.
