摘要

2002年6月至2003年5月於棲蘭神木園區、100線林道12至17公里及鴛鴦湖，沿主要道路進行鳥類調查，共紀錄22科71種，其中12種為台灣特有種，55種為留鳥，留鳥於本調查區域內佔紀錄種數的77%，為主要紀錄對象。以分類別而言，鶇亞科（11種）、畫眉亞科（11種）及鶯亞科（5種）合計佔紀錄鳥種的37%，為主要鳥種類別。全年單日最大量鳥總數為900隻，數量較多的鳥種依數量多寡排序為：冠羽畫眉（211隻）、藪鳥（84隻）、紅頭山雀（76隻）、白耳畫眉（56隻）、青背山雀（51隻）、棕面鶯（37隻）及小翼鶇（23隻）。此7種鳥類合計佔全年單日最大量鳥總數的60%，為本次調查範圍內的優勢鳥種。以分類群而言。畫眉亞科鳥類在鳥種數及鳥隻數上皆最多，在調查區內最為優勢。在季節變化上鳥種數及鳥隻數以數量多寡排列，依序皆為：夏季、秋季、春季、冬季。調查發現的山鷸、藍尾鴝、赤腹鶇、斑點鶇、紅尾鶇、白眉鶇、白眉地鶇、白喉笑等11種鳥類，為棲蘭林區鳥類的第一次記錄。

During the period of June, 2002 to May, 2003, a bird survey was conducted in the Chi-lan sacred tree garden, Chi-lan No. 100 forest lane (from 12 to 17 K), and Yuen-yang lake by observations held along the major paths. Seventy-one species of 22 avian families were recorded, among them were 12 endemic species of Taiwan and 55 resident bird species. Resident bird species took up 77% of the species recorded and were the major bird type in this study. Bird species of the subfamilies in Muscicapidae, Turdinae (11 spp.), Timalinae (11 spp.), and Sylviinae (5 spp.), summed up to 37% of the total bird species recorded, were the major taxonomic groups for this survey. The daily maximum bird number recorded of the whole observation year was 900. Species with higher daily amount listed in consequence were Taiwan Yuhina (Yuhina brunneiceps, 211 counts), Steere's Liocichla (Liocichla steerii , 84 counts), Red-headed Tit (Aegithalos concinnus , 76 counts), Taiwan Sibia (Heterophasia auricularis , 56 counts), Green-backed Tit (Parus monticolus , 51 counts), White-throated Flycatcher-Warbler (Abroscopus albogularis , 37 counts), and Blue Shortwing (Brachypteryx montana , 23 counts). The observed bird number of these 7 species took up 60% of the daily maximum bird number recorded of the whole observation year, which rendered them the dominant species in the survey area of this study. Birds of the subfamily Timalinae indicated the highest amount on both the number of species and counts, therefore, was identified as the dominant avian group in this area. The seasonal changes of species numbers were in coincidence with the seasonal changes of the bird counts, which showed a high to low sequence of summer, fall, spring, and winter. Eleven bird species encountered during survey period became the first time record for the Chi-lan forest area. They were Eurasian Woodcock (Scolopax rusticola ), Red-flanker Bluetail (Tarsiger cyanurus), Red-bellied Thrush (Turdus chrysolaus), Dusky Thrush (Turdus naumanni eunomus), Nauman's Thrush (Turdus naumanni naumanni), Eye-browed Thrush (Turdus obscurus), Siberian Thrush (Turdus sibiricus), White-throated Laughing Thrush (Garrulax albogularis), Great Tit (Parus major), Yellow-throated Bunting (Emberiza elegans), and Beavan's Bullfinch (Pyrrhula erythaca).
