摘 要
關鍵詞：社頂、大冠鷲、鳳頭蒼鷹、棲地選擇
1995年至2006年止12年期間，於大尖山、門馬羅山及社頂至鵝鑾鼻間的森林區域共發現48個大冠鷲巢位，這些巢位築於32棵巢樹上的36個位置。其中社頂自然公園和梅花鹿復育區以南的區域，巢位的數量由1995年的1巢，逐年增加至2006年的10巢，研究區域可能容納至少22個大冠鷲領域。比較巢附近和逢機取樣點的棲地變數差異以驗證大冠鷲的棲地特徵，發現研究區域大冠鷲的巢位處於較陡的坡度，有較高的樹冠層高度，較高的樹冠層鬱密度，較高的巢樹高度，距離建物、鋪面道路和小徑較遠，較大的植株斷面積總和，樹木胸徑在1-20cm, 20-40cm, .40cm以上的棵數亦較多。邏輯迴歸分析顯示坡度、樹冠層高度和距離小徑的距離三項變數對於區別巢位和逢機取樣點為較重要的變數。

A total of 48 breeding nests were discovered on 36 different displacements of 32 trees from 1995 to 2006 in the study area. The number of breeding nests increased from one in 1995 to 15 in 2006 in the south area of Sheding and Sika deer rehabilitation center. Whether the influence of afforestation, pasture land succession, and White Popinac (Leucaena leucocephala (Lam.) de Wit.) quickly expending connected the forest patches and fulfilled the gaps of forest thus an increasing of the breeding nests of Crested Serpent Eagle need further investigation. Compared to random sites habitat variables, Crested Serpent Eagle’s nest sites had steeper slope, higher canopy height, higher canopy closure, taller tree height, greater distance to a building, greater distance to a paved road, greater distance to a trail, bigger basal area for all trees in the plot, trees in the plot >1cm, 1-20cm, 20-40cm, .40cm. Logistic regression models indicated that slope, canopy height, distance to trail were the most important variables in distinguishing nest sites from random sites.
