摘要
为摸清广东从化无规定马属动物疫病区内野生鸟类分布、种群特点、活动规律和迁徙规律,2021 年9 月至2022 年8 月,采用样线法对广东从化无规定马属动物疫病区及缓冲区(以广州市从化区为核心的9 个区县)进行4 个季度、为期 1 年的野生鸟类多样性调查.共记录记录鸟类 146 种,隶属于 16目51 科;其中优势物种为暗绿绣眼鸟Zosterops simplex、红耳鹎Pycnonotus jocosus、白头鹎Pycnonotus sinensis、栗背短脚鹎Hemixos castanonotus、八哥Acridotheres cristatellus、金腰燕Cecropis daurica和黑短脚鹎Hypsipetes leucocephalus.在居留型组成方面,留鸟占总种数的 65.1%,冬候鸟占 21.9%,夏候鸟占9.6%.在区系组成上,东洋界占68.5%,古北界占 21.2%,广布种占 10.3%.记录到国家Ⅱ级重点保护鸟类17 种,省级重点保护鸟类23 种,列入濒危野生动植物种国际贸易公约(CITES)的 9 种.从化区和增城区的种群数量明显高于其他7 个区县;聚类分析表明,从化区与增城区的鸟类物种相似性更高.
Abstract
In order to understand the distribution,population characteristics,activity patterns,and migra-tion patterns of wild birds in the Conghua specified equine animal epidemic free zone and the buffer zones,i.e.9 districts including Conghua district as centre,seasonal wild bird survey was conducted using the line transect method from November 2021 to August 2022.A total of 146 species,belonging to 51 families,16 orders,was recorded.Among them,65.1%species were resident birds,21.9%were summer migrant,9.6%were winter migrant;68.5%birds were Oriental species,21.2%were Palaearctic species,and 10.3%were widespread species;17 species were listed in Grade Ⅱ key state-protected species,23 species in provincial protected birds,and 9 in Appendix Ⅱ of CITES.Seven species were dominant,including Zosterops simplex,Pycnonotus joco-sus,Pycnonotus sinensis,Hemixos castanonotus,Acridotheres cristatellus,Cecropis daurica,Hypsipetes leu-cocephalus.The population numbers in Conghua district and Zengcheng district were significantly higher than those in the other seven districts.According to cluster analysis results,Zengcheng district,out of the 8 buffer zones,shows the highest bird species similarity with Conghua district.
