摘要
本文用BBS方法 (Batchelder Bershad SimpsonScalingMethod)对笼养褐马鸡的社群等级进行了排序 ,发现其等级制度为近单线式。成鸟的等级明显高于亚成体 ,成年雄鸟的等级明显高于成年雌鸟。成年个体的等级与体重呈显著正相关 ,与面部红斑大小及耳簇羽长呈极显著正相关 ;全体 14只鸟的体重与体长及耳簇羽长呈显著正相关 ,与面部红斑大小呈极显著正相关。体重可以认为是直接与个体的争斗实力相关的参数 ,而面部红斑大小、耳簇羽长则可能是个体争斗实力的外在信号。在体重相近的雌性个体中 ,面部红斑和耳簇羽对社群等级有很大的影响。
A Brown Eared Pheasant Crossoptilon mantchuricum is a rare pheasants' species and endemic to China.From November 1998 to February 1999,the social hierarchy and its affected factors on a captive population of Brown Eared Pheasants were studied in Luyashan Nature Reserve of Shanxi Province,China.The dominance hierarchy was ranked with the Batchelder Bershad Simpson (BBS) Scaling Method.It was found that the dominance hierarchy of the captive Brown Eared Pheasants was a near linear.The hierarchy ranks of adults were significantly higher than that of subadults while the males' were significantly higher than females'.There were statistically significant correlations between the hierarchy scale values and the body weight,wattle size,ear tuft length.Statistically significant correlations were found between the body weight and body length,wattle size,ear tuft length.Body weight was the indicator of the fighting ability while the body length,wattle size and ear tuft length were the exterior signals of the fighting ability.It is suggested that the face might be the center of the fighting display in Brown Eared Pheasants.
