摘要
褐头鸫是国际受胁物种,繁殖地仅分布在我国的华北山地,迄今有关该物种的生态研究尚无专门报道。我们于2005年5月至2006年8月对北京和河北两地褐头鸫的巢址选择和活动区进行了初步研究。调查共发现褐头鸫的巢7个,其中北京百花山6个,河北雾灵山1个。巢址平均海拔1805m±86m(1730~1930m),巢树均为华北落叶松Larixprincipis-rupprechtii,巢树高度11.3m±2.2m(8~14m)。巢距地的平均高度为5.3m±1.5m(4~7m),巢址周围隐蔽性较好,天敌很难发现。2006年6~7月,利用无线电遥测技术在河北雾灵山国家级自然保护区对一只褐头鸫的雌鸟进行了无线电遥测,采用95%调和平均数法来计算,其繁殖期的活动区面积为1.93hm2±0.76hm2。
Grey-sided thrush (Turdus feae) is a threatened species which breeds in the mountain areas of northern China. There is limited information on the ecology of this species. From May 2005 to August 2006, the nest-site selection and home range of grey-sided thrush were studied in Beijing and Hebei Province. A total of 7 nests were found and the home range size of one female was obtained. The results showed that the average altitude of the nests was 1805 m ± 86 m ( 1730 - 1930 m). The average height of the nests was 5.3 m± 1.5 m (4 - 7 m), and the average height of the nest trees was 11.3 m ± 2.2 m (8 - 14 m). The nests were well covered by branches of Lar/x principis-rupprechtii. The home range of the one female in was 1.93 hm2 ±0.76 hm2, calculated by the harmonic mean contours (HMC) method.
