摘要

台北植物園植物種類超過l,000種，一年四季皆可見許多鳥類，本研究旨在調查台北植物園內之鳥類相現況，並與過去資料比較，對台北植物園之鳥類經營管理提出建議，以提昇該園教育及資源保育之功能。1995年6月至1996年5月在台北植物園調查47次（每月3-4次），共調查45種，11,632隻次鳥類，概分為留鳥30種，逸鳥10種，冬候鳥3種及過境鳥2種。麻雀、白頭翁、綠繡眼是優勢種，本調查出現頻率高於20%的有18種鳥類，與台北市野鳥學會過去14年，105次的19種相較，有13種相同，減少的有6種，新增的有5種。建議管理單位管制園內民眾音量，增加植物栽植面積，當可增加台北植物園鳥類資源的豐富度。人為野放的逸鳥是否對植物或其他野鳥造成影響，是值得繼續探討的課題。水生植物池是重要的棲息環境，應予妥善保留。

The Taipei Botanical Garden (TBG) contains more than 1,000 species of plants, and many birds can be found in the TBG all year round. The purpose of this study is to propose suggestions for bird management in the TBG, based on the results of 1 yr of observations. The information could enhance the TBG's functions of education and resource conservation. Birds in the TBG were observed 47 times (3-4 times each month) from June 1995 to May 1996. A total of 11,632 bird counts belonging to 45 species, including 30 species of residents, 10 species of escapees, 3 species of winter migrants, and 2 species of transients was recorded. Passer montanus, Pycnonotus sinensis, and Zosterops japonica were the dominant species. The occurrence probabilities of 18 species were higher than 20%. Compared with the result from a 14-yr survey of 105 observations conducted by the Taipei Wild Bird Society, the 2 results share 13 common species. Except for the extremely rare species (occurrence probability lower than 20%), 5 species newly occurred in this survey, but 6 old species disappeared. In order to increase the number of birds in the TBG, it is recommended that noise made by people should be controlled, and planted areas should be enlarged. Further studies are needed to determine whether escapees do harm to plants or influence the wild birds in the TBG. The ponds in the TBG are important habitats and should be preserved.
