摘　　要：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。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.
