臺灣地區外來椋鳥科（Sturnidae）鳥類的出現、分布與相對數量

The Occurrence, Distribution and Relative Abundance of Exotic Starlings and Mynas in Taiwan

Based on the databases of 1993-1999 provided by the Wild Bird Federation Taiwan and the Taiwan　 Endemic Species Research Institute, there were 10 exotic species of starlings and mynas belonging to the family Sturnidae in Taiwan. Acridotheres javanicus and Acridotheres tristis were the most common exotic species; each occurred in 36% of the total number of administrative units (towns, townships and districts) of the island. They were followed by Acridotheres fuscus and Sturnus nigricollis. The other six species were rare. They were Acridotheres albocinctus, Acridotheres ginginianus, Sturnus burmannicus,Sturnus contra, Aplonis panayensis and Gracula religiosa. Each of these species was found in less than 10% of the number of the administrative units. All exotic species were distributed primarily in lowlands,peripheral hills and mountains at elevations less than 500m. 本研究利用來自於中華民國野鳥學會及行政院農業委員會特有生物研究保育中心的三個資料庫，探討臺灣地區10種外來椋鳥科鳥類的分布。白尾八哥（Acridotheres javanicus）及家八哥（Acridotheres tristis）為其中最普遍的種類，其次為林八哥（Acridotheres fuscus）及烏領椋鳥（Sturnusnigricollis）。其餘六種，白領八哥（Acridotheres albocinctus）、岸八哥（Acridotheres ginginianus）、葡萄胸椋鳥（Sturnus burmannicus）、斑椋鳥（Sturnus contra）、輝椋鳥（Aplonis panayensis）及九官鳥（Gracula religiosa）數量仍不多。在臺灣361個鄉、鎮、區層級的行政區中，超過三分之一已有白尾八哥及家八哥的紀錄，其餘八種都在10%以下。10種外來椋鳥主要分布於平原及週遭低於海拔500m以下的丘陵地帶。
