摘要

From Apr. 1993 to Apr. 1994 at Sheting, 5 sika deer (Cervlls nippon taiollanlls) were selected to study their feeding behavior in different seasons. Feeding behavior was divided into 4 categories according to browsing level: (1) low (height under-shoulder), (2) medium (height over-shoulder but no more than the height of full neck stretch with 4 legs on the ground), (3) high (height over medium including jump ... etc.) and (4) reef (climbing coral reef to feed). The relative occurance of different feeding behavior used by deer were: low (80.5%), medium (15.4%), reef (3.4%) and high (0.7%) respectively. The occurance of four behaviorial categories also varied between seasons. Deer climbing reef to feed increased significantly from 0.2% in wet season (Oct. to Apr.) to 5.2% in dry season (May to Sep.) (ANOVA, p＜0.05); while the occurance of feeding under shoulder height decreased from 86.9% in wet season to 76.8% in dry season (ANOVA, p＜0.05). The seasonal changes of relative frequency of foraging behavior implied that the relative abundance and availability of the forest undergrow in different seasons played an important role of deer feeding behavior.
