丹大野生動物重要棲息環境之巒大事業區135-148林班鳥類群落調查從102年秋季至103年夏季,分別於巒大事業區140、142及143林班三個林班各選擇1處進行鳥類定點計數估算密度,並透過沿線調查記錄郡大林道31K~37K路線上所發現之物種,共計巒大事業區135-148林班範圍內記錄21科33種,其中特有種有12種,特有亞種有14種,保育類14種,春夏季數量以冠羽畫眉(Yuhina brunneiceps)最為優勢。巒大事業區135-148林班外之郡大林道31K~37K路線上共發現20科33種,特有種記錄到11種,特有亞種記錄到15種,保育類則有9種。根據定點計數結果,秋季記錄6種,冬季記錄5種,春季記錄13種,夏季記錄13種,秋冬季記錄的物種較少,春夏季物種較為豐富;而根據沿線調查結果,秋季記錄21種,冬季則僅15種,春季紀錄23種,夏季紀錄26種,冬季物種及數量相較少於其他季節,由於鳥類於冬季會有海拔垂直降遷的行為,因此冬季於高海拔記錄的鳥類物種相對減少,繁殖季時則可記錄到較多物種。 Bird community surveys of the Danda Major Wildlife Habitat of the Luanda Working Circle were conducted from 2013 fall to 2014 summer. Avian point-counts were sampled at 3 sites in 140, 142, and 143 compartments of the Luanda Working Circle seasonally. Observational surveys were also conducted from 31K to 37K of the Jyunda logging road. Total 33 species belonging to 21 families were found in 135-148 compartments of the Luanda Working Circle, including 12 endemic species, 14 endemic sub-species, and 14 protected wild birds. Taiwan yuhina (Yuhina brunneiceps) was the most abundant during the breeding season. Along the Jyunda logging road outside 135-148 compartments of the Luanda Working Circle, 33 species belonging to 20 families were found, including 11 endemic species, 15 endemic sub-species, and 9 protected wild birds. Avian point-counts documented 6 species in fall, 5 species in winter, 13 species in spring, and 13 species in summer. The species found in fall and winter were fewer than in spring and summer. Along the Jyunda logging road outside 135-148 compartments of the Luanda Working Circle, there were 21 species in fall, 15 species in winter, 23 species in spring, and 26 species in summer are found. The species found in winter were fewer than the other seasons. Fewer bird species in winter were resulted from altitudinal migration of some birds in winter.

Sampling Methods

定點計數 定點計數法調查時採不定半徑圓圈法(variable circular-plot method) (Reynolds et al., 1980),記錄停留時目擊和聽聞的鳥種、數量、鳥隻與研究者的水平距離、方位及發現時間等,對於持續於空中飛行的種類[如燕科(Hirundinidae)、雨燕科(Apodidae)、鷲鷹科(Accipitridae)],由於較難確認其棲地使用範圍及類型,因此不列入分析。每處記錄6分鐘且皆於日出後4小時內完成,以方便比較(丁宗蘇,1993)。 繁殖季的特定基礎半徑內所記錄的總隻數,以聽到1次鳴叫聲乘以2作為加權值;非繁殖季若為結群鳥種則同一群僅記錄1次,再乘以該鳥種的平均結群隻數,非結群出現鳥種,1次鳴叫聲仍以1隻個體計算。 平均結群隻數的計算方式,係參考雪山地區(孫元勳,2013)非繁殖季(2009年1月、2010年10月至2011年2月)目擊記錄到的結群鳥種隻數進行平均。 用來計算密度的鳥類特定基礎半徑為由本調查結果計算,惟部分鳥種記錄不足,則參考丁宗蘇(1993)及廖煥彰(2006)所使用的鳥類特定基礎半徑加以運算。 沿線調查 於郡大林道31K~37K(海拔落差不超過100公尺)進行沿線調查,記錄資料包括地點、海拔、物種、數量及發現方式等,此資料並不使用於鳥類密度計算,僅列入本研究鳥類名錄及海拔分析之中,以建立較為完整的鳥類資料庫。 調查期間如遇到下雨或風大則無法進行鳥相調查,如2013年秋季受颱風影響,僅收集到一處的資料,其它兩處則因為風勢過大而無法進行定點計數,亦無資料蒐集。所有定點計數點位及棲地類型詳見表1。鳥類名錄依據TaiBIF(臺灣生物多樣性資訊入口網,http://www.taibif.org.tw/)的資料製作。
