红腹角雉取食栖息地选择的研究

STUDY ON THE RELATION BETWEEN HABITAT SELECTION AND DIET OF TEMMINCK'S TRAGOPAN *

１９９３年１１月～１９９４年１０月，在以无线电遥测技术对贵州省仙人山地区红腹角雉Ｔｒａｇｏｐａｎｔｅｍｍｉｎｃｋｉ的活动范围、栖息地选择及食性研究的基础上，对其取食栖息地的选择作了探讨。红腹角雉遥测位点和粪便相对集中分布，表明对栖息环境存在明显的选择，对食物分布的样方分析表明其活动特点与食物密切相关。红腹角雉各季节主要活动于多灌木与草本植物的沟谷带上段，春冬季主要取食草本及蕨类植物，活动范围较大，并常在雨雾天到谷底小道上段取食；夏秋季主要取食成熟的灌木及乔木的果实，活动范围较狭小固定。

A study on home range,habitat selection and diet of Temminck's Tragopan ( Tragopan temminckii ) with telemetry was performed from November 1993 to October 1994.The distribution of radio locations and droppings were relatively concentrated.The distribution of its food items indicated that the habitat selection of T temminckii was closely relevant to its diet.The preferred habitat situated in the part of the higher elevations and within 100m along the path in the valley with rich bushes and herbs.In spring and winter, T temminckii fed mainly on herb and ferns and its home range size was larger.In rainy and foggy weather, T temminckii occured often on the path of valley.In summer and autumn,its food was the mature fruits and its home range was smaller and more regular than that in spring and winter.
