红腹角雉的食性研究

THE STUDY ON DIET OF TEMMINK’S TRAGOPAN*

１９９３年１１月至１９９４年１０月，利用无线电遥测装置，以直接观察法、取食痕迹检查法为主，以粪便分析法和嗉囊及胃内容物分析法为辅，对贵州仙人山地区红腹角雉全年的食性作了研究。获知其取食８７种食物，其中植物性食物占９４３％，动物性食物占５７％。春、夏、秋、冬的食物种类分别为５９、２８、２４、４４种。红腹角雉的食性存在区域性及季节性差异，同时又有一定的重叠性。食物种类广泛，未发现对某种食物特别依赖，与同属的黄腹角雉不同，这是红腹角雉较黄腹角雉分布范围广、适应能力强的一个重要原因。

お? From November 1993 to October 1994,the diet of Temminck’s Tragopan (Tragopan temminckii) was studied in Xianrenshan area of Guizhou Province with field observations,trace checking,dropping analysis and crop examinations Radiotelemetry was used for tracing three Temminck’s Tagopans The results of diet analysis were as follows: Temminck’s Tragopan performed 5 types of feeding patterns,e g pecking,digging,jump-feeding,chase-feeding and feeding on trees with pecking as the main pattern They moved to rugged areas in snowy weather;and prefered to feeding along the trails in valleys when it’s raining or foggy This behaviour is closely related to the food supplies The pheasant was found to have 87 food items throughout the year The food items of Spring,Summer,Autumn and Winter were 59,28,24 and 44,respectively The diet was significantly different between seasons In the same season,the diet varied with areas and individuals Generally,Temminck’Tragopans fed on a variety of herbs and ferns in winter and spring In summer and autumn,they fed on fruits of several species of bushes and trees,as well as herb seeds The fruit of Alangium chinense and Macrocarpium chinensis were the main food in autumn Different from Cabot’s Tragopan,Temminck’s Tragopan feed on a number of different kinds of food without relying on one of them This is probably one of the important reasons that Temminck’s Tragopan has larger distribution area and is more common than Cabot’s Tragopan
