外來鳥－白腰鵲鴝 (Copsychus malabaricus) 已成功入侵臺灣。依據賞鳥者的目擊紀錄、
中華民國野鳥學會鳥類資料庫1988-2007、文獻紀錄、本研究2006-2008 的野外調查及2007-2008的移除計畫等資料，探討此鳥種在臺灣野外之分布及族群數量。此鳥種主要分布在臺灣西部海拔400 公尺以下的丘陵地帶。在1988 年即出現在臺灣野外，但直到近年才記錄到其在野外繁殖與建立族群，且從雲林縣林內鄉湖本村之族群數量變化顯示，初期數量低但從2005 年後急速
成長。目前其成功建立族群的區域仍侷限在臺灣西岸的中南部地區，但不同於以往已入侵臺灣
的外來鳥種，白腰鵲鴝能夠侵入低海拔的天然森林中。因此，建議在其野外族群數量仍低且分
布侷限時，及早執行移除和管控工作，以掌握解決問題的關鍵時機。

The White-rumped Shama (Copsychus malabaricus) is an alien invasive species in Taiwan. The distribution and
abundance of this species was estimated based on recorded observation of active birders, the database of 1988-2007 provided by the
Chinese Wild Bird Federation, literature citation, a field survey conducted from 2006 to 2008 and an eradication project conducted
from 2007 to 2008. This species was found primarily in the western hilly areas of Taiwan at elevations below 400 m. Since it was
first recorded in the wild in 1988, it has bred in recent years resulting in confirmed sustainable feral populations in Taiwan. The
population sizes of the species in Huben Village, Linnei Township, in Yunlin County remained low originally but the rate of
increase steadily increased after 2005. However, the areas where this invasive feral population has established itself are still
confined to southern and central-western Taiwan. Unlike earlier avian invaders in Taiwan, the White-rumped Shama has the ability
to invade lowland natural forest areas. Therefore, it is recommended that proactive control management is executed at a time when
their population is still limited in number and localized.
