灰胸薮鹛活动区的无线电遥测研究

The Home Range of Liocichla omeiensis by Radio Tracking

2016年1—2月和6—8月,分别在四川省峨眉山和四川老君山国家级自然保护区,利用无线电遥测技术对灰胸薮鹛Liocichla omeiensis非繁殖季和繁殖季活动区进行了初步研究。结果表明:灰胸薮鹛非繁殖季的平均活动区面积为9 659 m2±975 m2(95%FK),平均核心区面积为2 542 m^2±263 m^2(60%FK)(n=4);繁殖季的平均活动区面积为13 040 m^2±6 003 m2(95%FK),平均核心区面积为1 581 m^2±1 362 m^2(60%FK)(n=2)。非繁殖季遥测个体间的活动区重叠百分率基本在50%以上;而配偶间的活动区重叠面积在70%以上。该现象可能与是否配对、领域行为及栖息地质量有关。此外,还发现灰胸薮鹛的日活动具有节律性,雌鸟和雄鸟分别在早、晚和早、中、晚各有1个活动高峰期。

Home ranges of Emei Shan Liocichla （ Liocichla omeiensis） during non-breeding season （ from January to Feb-ruary） and breeding season （ from June to August） were studied using radio tracking techniqSichuan Laojunshan National Nature Reserve, respectively. The results showed that, in non-breeding season, the home-range estimates with Fixed Kernel （60% , 9 5% ） were 2 542 m^2 ±263 m^2 and 9 659 m^2 ±975 m^2（ n = 4） ,and those in breeding season were 1 581 m^2 ± 1 362 m^2 and 13 040 m^2 ±6 003 m^2（n = 2）, respectively. The percent overlapping home ranges bet^veen individuals were largely over 50% in non-breeding season, and bet^veen the mates were more than 70% .This phenomenon was probably linked to the pairing, territorial behaviors and habitat quality. In hibited obvious diurnal-movement rhytlim. The female and male had 2 （i. e. morning and evening） and 3 （i. e. morning, noon and evening） activity peaks, respectively.
