2008年5月至2009年11月,采用固定样点法对广东省珠海市担杆岛的鸟类进行了调查。共记录到鸟类74种,其中留鸟29种、候鸟45种。雨季记录到鸟类45种,旱季记录到鸟类48种。雨季与旱季每个样点平均记录到的鸟类种数分别为3.5种(n=80)和3.7种(n=69),差异不显著(Z=-0.86,P=0.39);鸟类个体数分别为9.7只(n=80)和12.9只(n=69),差异显著(Z=-2.19,P=0.03)。20世纪80年代和本次调查2个时期共有鸟类仅11种,有 5个常见种本次调查未记录到,而20世纪80年代有记录;本次调查的6个常见种20世纪80年代未记录到,当地鸟类迁入和迁出的原因有待探讨。
Abstract: The birds at Dangan Island, Guangdong were surveyed by point counts from May 2008 to November 2009.Seventy-four species were recorded. Among them, twenty-nine species were residents, forty-five ones were migrants. Forty-five and forty-eight species were recorded in the rain season and dry season, respectively. There were no significant differences between the rain season and dry season on the mean species richness per point (3.5 vs. 3.7, Z=-0.86, P=0.39), but there were significant differences on mean abundance per point (9.7 vs. 12.9, Z=-2.19, P=0.03). There were 11 shared species between 1980-1981 and 2008-2009.Five common species, which recorded in 1980-1981 were not seen in 2008-2009.Other six common ones, which recorded in the present survey, lacked in 1980-1981.More concerns are needed to explain the reasons of common immigrant species and emigrant species in the future.
