摘要: 底层地面活动鸟类由于行为隐蔽,野外调查较困难。于2011年1月—2017年3月,利用红外相机监测技术在广东北部3个自然保护区开展底层地面活动鸟类监测,共拍摄到54种鸟,其中在南岭、车八岭和南雄分别拍到鸟类47种、27种和21种。广东北部森林底层地面活动优势鸟种是白鹇(Lophura nycthemera)和黑领噪鹛(Garrulax pectoralis)。平均每台红外相机拍到鸟类4种,并且三地差异非常显著,以南岭最高、南雄最低;平均每台红外相机拍到鸟类32只,但三地差别不明显。在广东北部森林用红外相机拍到的底层地面活动鸟类种类比周边地区多,与安放的红外相机数量多、拍摄的时间长有关。依据本研究和近年来在广东北部的鸟类调查结果推断,广东可能已经没有白颈长尾雉(Syrmaticus ellioti)和勺鸡(Pucrasia macrolopha)的分布。

Abstract: Forest birds are difficult to be detected because of their cryptic behaviors. In this study, camera trapping technology was used to monitor such birds in three forest sites of northern Guangdong. At Nanling National Nature Reserve, Chebaling National Nature Reserve, and Nanxiong Provincial Nature Reserve, 124, 66, and 29 cameras respectively were set up to monitor forest birds between January 2011 and March 2017. A total of 2659, 1063, and 769 photographs were produced, respectively. In total, 54 species were cameratrapped at the three sites, with 47species at Nanling, 27 species at Chebaling, and 21 species at Nanxiong. Lophura nycthemera and Garrulax pectoralis were the dominant species in those forests. The mean number of species recorded per camera was four. There were significant differences in species richness among the three sites, with the highest species richness in Nanling and the lowest in Nanxiong. No significant differences were found among the three sites for the mean number of individuals recorded per camera. Species richness in northern Guangdong appeared to be much higher than that at nearby sites, such as at Badakongshan in Hunan, and Huaping in Guangxi. Such differences might be related with the use of a larger number of cameras over a longer period. Syrmaticus ellioti andPucrasia macrolopha were not detected during cameratrapping at the three northern Guangdong sites and in other transect survey in northern Guangdong in past decades. We speculated that bothspecies may have been locally extinct.
