基于红外相机技术的雷公山国家级自然保护区鸟类调查研究

Bird Survey in Leigongshan National Nature Reserve Based on Infrared Camera Technology

为掌握雷公山国家级自然保护区野生鸟类资源状况,采用公里网格随机布设60个红外相机监测位点,对雷公山重点区域地面活动鸟类进行调查。2020年1月至2021年12月,100台红外相机野外累计正常工作18074个相机日,累计获得独立有效鸟类照片(视频)2883份。调查监测记录到鸟类7目、17科、48种,其中栗苇鳽、红点颏、蓝歌鸲、斑胸钩嘴鹛、灰头绿啄木鸟、灰翅噪鹛、褐翅鸦鹃等7种为雷公山保护区鸟类新纪录。分析结果表明:鸟类相对多度最高为白鹇,其次为灰胸竹鸡和棕头鸦雀;鸟类网格占有率最高为白鹇(42.05%),棕头鸦雀(35.23%)和灰胸竹鸡(25.00%)次之。

In order to grasp the status of wild bird resources in Leigongshan National Nature Reserve,60 infrared camera monitoring points were randomly arranged using a kilometer grid to investigate ground active birds in key areas of Leigongshan.From January 2020 to December 2021,100 infrared cameras worked normally in the field for a total of 18074 camera days,and a total of 2883 independent and effective bird photos(videos)were obtained.The investigation and monitoring recorded 48 species of birds in 17 families and 7 orders,among which 7 species were new records of birds,including Ixobrychuscin namomeus,Calliope calliope,Luscinia cyane,Pomatorhinus erythrocnemis,Picus canus,Garrulax cineraceus and Centropus sinensis.The analysis results showed that the relative abundance of Lophura nycthemera was the highest,followed by Bambusicola thoracica and Paradoxornis webbianus;the highest bird grid occupancy rate was Lophura nycthemera(42.05%),followed by Paradoxornis webbianus(35.23%)and Bambusicola thoracica(25.00%).
