摘要

本研究欲探討在不同季節下，雌性台灣環頸雉活動範圍之棲地組成與各類棲地及活動模式在季節間的差異。實驗由2003年3月至2004年2月於新光兆豐休閒農牧場進行。研究中利用無線電追蹤13隻雌性台灣環頸雉的活動範圍及活動模式，並分析其中對各類棲地利用狀況。在活動範圍方面，各季節間以最小凸多邊形估計活動範圍面積，其各季平均以夏季17.5公頃最大，依次為春季10.4公頃，秋季8.8公頃，最小為冬季5.3公頃。而環頸雉棲地利用情形可分成兩類，春夏秋季多數個體日夜間使用同一種棲地，秋季多數個體日夜間使用不同類棲地。不論是定位點超過50%比例的棲地類型，或X2 test檢測所偏好的棲地，春夏季不論日間或夜間個體間所偏好與利用的棲地類型相異，秋冬季多數環頸雉日間偏好利用低牧草地與果園，夜間則為低牧草地。不同季節雌性環頸雉的活動模式也有差別，其中夏季為晨昏高峰，而春秋冬季日間各小時相對活動量相似。

We used radiotelemetry to minitor the home range, activity pattern, and habitat use by 13 female Formosan Ring-necked Pheasants (Phasianus colchicus formosanus) at Chao-Fon Farm in Hualien from 2003.3 to 2004.2. The result showed that the home range was largest in summer (17.5 ha) and smallest in winter (5.3 ha). And they were 10.4, and 8.8 ha in spring and fall, which were calculated by Minimum Convex Polygon (MCP). Habitat use by female pheasants had two types. Most of females used the same habitat during the day and night in spring, summer and winter. In fall, most of females used different habitat between the day and night. Females preferred different habitat during in spring and summer. While in fall and winter, they preferred Low pasture and orchard during the day, and Low pasture at night. Females’ hourly activity ratios were observed that all similar during the day in spring, fall and winter. However, it was higher in the early morning and late afternoon, and lowest at midday in summer.
