台灣鉛色水鶇海拔分布之季節性變化

Seasonal Variation in Altitudinal Distribution of Plumbeous Water Redstart (Rhyacornis fuliginosus affinis) in Taiwan
作者 蘇美如張世倉林瑞興 (Ruey-Shing Lin)
中文摘要
本研究利用泛布全台的86條穿越線調查資料說明台灣鉛色水鶇(Rhyacornis fuliginosus affinis)部分族群的季節性垂直遷移行為。資料分析發現冬季(11-2月)有鉛色水鶇紀錄的穿越線海拔(527±467m, n=77)低於非冬季(4-9月)有紀錄者(732±637m, n=43),但差異未達顯著水準(U-test, p =0.067);另由非冬季至冬季各穿越線鉛色水鶇數量有隨海拔下降而上升的趨勢。上述結果顯示雖然冬季與非冬季鉛色水鶇的海拔分布有相當程度的重疊,但至少有部分鉛色水鶇會於冬季進行垂直遷徙,移向海拔較低的棲息地。 Altitudinal distributions of the plumbeous water redstart (Rhyacornis fuliginosus affinis) in Taiwanwere analyzed, using the data collected from 86 transects by the bird inventory survey conducted by theEndemic Species Research Institute, 1994 to 2004. They were compared between the winter season(November to February) and the non-winter seasons (April to September). The plumbeous water redstartswere observed from 77 transects at the elevations of 527±467m (mean±SD) in the winter season, andfrom 43 transects at 732±637m in the non-winter seasons. There was no significant difference in the elevations between the two seasons (U-test, p = 0.067). However, the number of the birds at each of thetransects increased with the decrease in elevation from non-winter season to the winter season,suggesting that some of the plumbeous water redstarts did migrate to lower elevations in the winterseason and to higher elevations in the non-winter seasons.
