董寨国家级自然保护区人工巢箱招引鸟类研究

目的]了解近年来董寨国家级自然保护区人工巢箱对鸟类的招引情况。方法]利用2008年在保护区内悬挂的100个人工巢箱,分析2008~2013年间鸟类对人工巢箱的利用规律。结果]董寨保护区招引的鸟类主要为红角鸮(Otus sunia)、麻雀(Passer rutilans)、大山雀(Parus major)、山麻雀(Passer rutilans)和丝光椋鸟(Sturnus sericeus)。2008~2013年每年鸟类对巢箱的利用率为17%~34%,且有重复利用旧巢的习性。此外,鸟类对巢箱的利用率整体上呈逐年下降趋势,这可能与保护区内植被逐年恢复,可供利用的自然巢址逐年增加有关。巢箱的位置对巢箱的招引效果具有一定的影响,以山坡下林缘的巢箱招引效果较好。结论]在今后的人工巢箱悬挂中,应该优先选择在森林下部的边缘进行悬挂,以起到更好的招引效果。

Study on Bird Attraction Using Artificial Nest Boxes in Dongzhai National Nature Reserve

Objective] The aim was to understand bird attraction using artificial nest boxes in Dongzhai National Nature Reserve .Method] U-sing 100 artificial nest boxes in 2008, the utilization law of birds to nest boxes during 2008-2013 was analyzed.Result] The main birds attrac-ted in Dongzhai National Nature Reserve included Otus sunia, Passer rutilans, Parus major, Passer rutilans, Sturnus sericeus.During 2008 -2013, the utilization rate of birds to nest boxes was 17%-34% every year, and had the habit of repeating old nest.The utilization rate showed a downward trend year by year , which may be related to restoration of vegetation in protected area and available natural nest sites increased year by year.The location of nest boxes had a certain effect on birds attraction, the hillside forest edge was better.Conclusion] In the future the sus-pension of artificial nest boxes should be preferred in the edge of forest lower part , so as to better attract birds.
